The Cost of Selling Your Tesla and Buying a Newer Model
With Tesla constantly releasing new updates, it’s inevitable that your newly purchased Tesla will one day feel outdated. A prime example would be the flood of RWD Model S’ that hit the second hand market after Tesla announced that it would release the dual motor “D” variant. And now with the Model X available, Model S owners are thinking about trading in their beloved electric sedan for the newest shiny Tesla with falcon wing doors. I would be one that falls into this category. Here’s my analysis on what it would cost to upgrade to a newer Tesla.
A short while ago I configured a Model X and a Model S to specifications that I would buy in present day. This came out to $103,200 and $88,450 respectively after available tax credits. For reference my current Model S cost me $92,443 after tax credits.
Understandably, Tesla does not offer a retrofit for the autopilot hardware though we calculated a hypothetical $67,000 cost to upgrade if it were available. Maybe one day Tesla will offer upgradeable hardware but for now having recurring firmware updates that refreshes functionality on the car isn’t so bad.
Trade Ins
If I were to use Tesla’s math to compute trade in value for my 21 month old Model S with 55,000 miles, it would theoretically have a value somewhere along these lines:
This math is clearly not accurate, and since I was seriously considering the Model X or a newer Model S, I asked Tesla for a true trade in value.
Tesla came back with a trade in value of $49,200. Their resale price as a CPO vehicle would be $55,100:
This is a heck of a lot better than the original formula, but I’ve still used 48% of the original value in less than 2 years. At this trade in value, the effective cost of trading up to new X or S would be $54,000 and $39,250, respectively.

CPO Comparisons
My trade in value made me curious on what other CPOs sold for so I hit up the excellent EV-CPO Consolidator which provides a great deal of information about Tesla CPO cars.
Browsing that site you’ll be hard pressed to find a 2014 Model S with anything close to my mileage. The closest I found was a 2014 Model S in Los Angeles with 48K miles listed for sale at $55,600, just a bit above the quote I got. I don’t know if that car is in as good a shape as mine (I’ve seen some really beat up CPO cars), but the pricing, age and configuration are at least consistent with my quote.
As you’d expect mileage and available features make the most difference in the CPO price. 2014 S85 model CPO prices can range from a low of $55,600 to $79,200 for a low mileage, late 2014 loaded Model S. Within New England the range is only from $56,200 to $67,400.
Kelly Blue Book
Next stop was Kelly Blue Book. Their trade in value came in between $49,305 and $57,740 with an average of $53,549. My Model S, before taxes, was $93,970. So the trade in price per Kelly Blue Book is 57% of the original price.
If you believe the KBB quote, Tesla is on the low end of the trade in values. This seems to be consistent with some posts I’ve seen on TMC and the Tesla forum. If you find your own dealer and trade directly with them you can potentially increase your trade in value by up to $5,000. If you sell privately you may be able to get up to $10,000 more over Tesla’s offer.
Selling privately however can bring its own set of problems, especially in states like Massachusetts where there are strong Lemon Aid Laws that allow individuals to buy a car, drive it for 7 days and then bring it back for a 100% refund if for some reason there’s an issue with state inspection. Selling privately also comes with a huge commitment to arrange for test drives and educate your driver on how to operate an EV. Here in New England EVs aren’t everywhere yet and the Tesla is still a rare car to see.
Competitive Comparisons
To see how other cars “in the same class” compare to the Model S in terms of trade in value, I picked the Porsche Panamera S. E-hybrid to benchmark against. The average trade in value for that car is $53,746 which is very comparable to my Model S. Configuring a Panamera will drive you crazy but it seems that a new one similarly configured would go for $95,270 before taxes. So the trade in price per Kelly Blue Book is 56.4% of the original price, which is about the same as the Model S.
According to EVObsession, the Mercedes S-Class was #1 in the Large Car Luxury Market in 2014, but the Model S blew past that in 2015. I came up with a new price of $91,328 and an average trade in value (same mileage/year as mine) of $57,782 or 63.2% of the original price — the Mercedes seems to retain a bit more value although they’re still in the same range.

Summary
That very first mile you put on your new car has a huge effective cost whether it’s on a Tesla or any other car from a different manufacturer. Trade in values for Model S’ are in line with other cars in its class, although Tesla’s trade in value tends to be on the lower end of the spectrum.
If you’re looking to get top dollar for your used Model S, consider trading it in to a company other than Tesla or selling your Model S privately. Both bring additional levels of hassle but that extra lift can be worth the additional value.
Even if I were to receive $5,000 over Tesla’s trade in value, I’d still be looking at an upgrade cost of over $30,000 to trade up from my Model S (which is less than 2 years old) to a new dual motor Model S with autopilot, upgraded seats, and all of the other improvements and tweaks Tesla made over the last couple years. Is it worth it?
If the gap was closer perhaps the decision would be a lot easier, but in this range for me, and with the recent news that Tesla will be adding more autopilot hardware in the future, I think keeping my Model S and enjoying it is the right way to go.
Besides, with more Model Xs hitting the streets every day, the all wheel drive “D” Model S will inevitably start appearing as CPO inventory. This will open up a whole new world of options. Wait and see is probably still the best choice for those looking to trade up from an earlier Model S.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”
We took a ride on a robotaxi on the Suntrax course and it successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.

Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.

The real reason Elon Musk wants every car connected to space
Elon Musk says all cars will eventually need Starlink to handle massive AI bandwidth demand.
Elon Musk is making the case that satellite internet, not fiber or cellular towers, will end up wired into every car on the road. In a string of posts on X, the SpaceX CEO wrote that all cars will have Starlink in the future and called satellite connectivity the only way to get super high bandwidth to billions of vehicles.
The posts started with Musk endorsing a Cloudflare forecast that traffic generated by autonomous AI agents will soon dwarf traffic generated by humans browsing the internet, a shift he described as not a close call at all. From there he narrowed the argument to infrastructure, writing that the only system that can support the insanely fast bandwidth growth needed by AI is Starlink, before extending the logic to cars specifically.
AI agentic Internet traffic will obviously VASTLY exceed human usage. Not a close call at all.
Cloudflare’s forecast is accurate. https://t.co/VztgrinN5k pic.twitter.com/Wo4FiRKjPU

The timing lines up with Tesla’s own hardware decisions. On July 20, Tesla confirmed the Cybercab would ship with a Starlink V5 terminal built into its roof, the first time the company had put satellite hardware in a production vehicle. A day later, Tesla’s head of AI, Ashok Elluswamy, explained the connection wasn’t there for safety and that Cybercab’s driving stack runs entirely on onboard cameras and compute, while the satellite link exists for navigation, customer service, and fleet management instead. Musk followed with his own post about the feature, saying riders would be able to watch 4K streaming video during rides.
By July 22, Musk had already said Starlink would extend beyond Cybercab to Tesla’s full lineup. Sunday’s posts push that same logic outward again, this time framed as a requirement across the industry rather than a feature specific to Tesla, and tied directly to the bandwidth AI systems are expected to consume.
SpaceX’s newest Starmind will make earth data centers obsolete
-
The AI argument has been building on SpaceX’s side for months. The company has an FCC filing pending for a third generation Starlink constellation, and it has separately proposed Starmind, a constellation of up to a million satellites designed to run AI computation directly in orbit rather than just relay data. Musk has said he expects space to become the cheapest place to deploy AI compute within two to three years. Starlink and Starmind serve different jobs inside that vision, one moving data and the other processing it, but Sunday’s posts treat vehicles as one more category of hardware that will eventually need both.
None of this changes anything for Tesla owners today. Cars already on the road keep running on LTE and Wi-Fi, and Tesla hasn’t outlined a retrofit path for existing vehicles. The July 22 commitment applies to future production, not the fleet already delivered. What Musk added on Sunday is the reasoning: satellite connectivity isn’t a Cybercab novelty, it’s a bet that ground based networks won’t keep up with how much data cars, robots, and AI systems are about to generate.

The Boring Company’s newest tunnel vehicle runs on Tesla parts and no one is driving it
The Boring Company’s new tunnel vehicle runs on Tesla Model 3 batteries and drive units.
The Boring Company just introduced a new piece of hardware, and it runs on parts pulled straight from a Tesla showroom. Liner Truck 3, unveiled in a post from the tunneling company’s official X account, is an all electric vehicle built around Tesla Model 3 battery packs and drive units, purpose built to move concrete tunnel segments to the boring machine face without a single person underground.
Introducing Liner Truck 3 — our latest fully electric tunnel vehicle.
– Tesla Model 3 battery and drive units
– Transports 22,000+ lb of concrete segments to the boring machine
– 28 miles of range
– 12 mph max operating speed
– Remotely piloted from Global OCC in Texas, with… pic.twitter.com/XB7FgSXnpy— The Boring Company (@boringcompany) August 7, 2026
The job itself is unglamorous but critical. Each precast segment run weighs more than 22,000 pounds, roughly the load of a full cement mixer, and Liner Truck 3 hauls that weight repeatedly between the surface staging area and wherever the Prufrock machine happens to be cutting.
The Boring Company said Liner Truck 3 is piloted remotely out of its Global Operations Control Center in Texas, extending the Zero-People-In-Tunnel approach the company has spent years building toward. An earlier version of a ZPIT liner truck was already tested at the company’s Bastrop, Texas research tunnels, and a factory tour released last month showed an employee flying a fully loaded liner truck with a PlayStation controller. Liner Truck 3 looks like the production version of that same idea, cleaned up and pushed into daily use.
The timing lines up with a company digging in more places than it ever has before. The Boring Company now has multiple Prufrock machines active or arriving in Nashville, where Music City Loop construction has been accelerating since February, and its Vegas Loop network keeps adding tunnel mileage on a near monthly basis. Every one of those projects depends on getting concrete segments to the cutting face fast enough to keep the boring machine from idling, which is exactly the bottleneck Liner Truck 3 is designed to remove.

It also reinforces something Tesla owners have watched happen gradually across Musk’s companies: passenger car hardware finding a second life in heavy equipment. Model 3 drive units already move people through the Vegas Loop, and now the same components are hauling concrete underground in Nashville and wherever The Boring Company digs next. Whether that kind of component reuse extends further into TBC’s equipment lineup, or into other Musk owned industrial hardware, is the next thing worth watching.
