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With Tesla constantly releasing new updates, it’s inevitable that your newly purchased Tesla will one day feel outdated.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.

Elon Musk drops a surprise update on Boring Company’s next big dig
Musk says Boring Company could shrink the Austin to San Antonio drive to just minutes.
Elon Musk says The Boring Company is working on what he called “a simple, precursor Hyperloop” tunnel connecting Austin and San Antonio, targeting speeds above 200 mph and cutting a drive that can take up to two and a half hours down to a consistent under 30 minutes. Musk posted the idea on X Sunday, in a reply to a repost of an AI generated video imagining a science fiction future with human colonies on other worlds, which he shared with the line “This is the future we shall bring into being.”

The Boring Company’s own account picked up the idea in the same thread, adding a detail about how the trip would actually work: “Because Loop/Hyperloop is express (i.e. no intermediate stops), one could travel from an Austin parking lot to a favorite San Antonio restaurant in about 30 minutes. As long as they both have Loop stations.” That framing ties the proposed intercity link to the same station model the company already runs in Las Vegas, where riders enter the tunnel network through small, garage style stops rather than one central terminal.
This is not the company’s first run at the Austin to San Antonio corridor. Boring Company floated tunnels between the two cities as far back as 2021, and later competed for a separate San Antonio Loop project tied to the airport before that specific bid stalled. Pitches for tunnels in Chicago, Los Angeles, and a New York to Washington corridor have followed a similar pattern of big announcement without a shovel in the ground.
What is different this time is the balance sheet, especially since The Boring Company closed a 3 billion dollar funding round led by investors in the United Arab Emirates earlier this month at a valuation near 23 billion dollars, giving the tunneling company more capital to chase speculative projects than it had during its earlier Texas pitches. The company is also mid-build on two other intercity systems it has actually broken ground on, inc;luding a Nashville tunnel linking downtown to the airport, where a second boring machine finished commissioning in June, and its Las Vegas network, where the station count keeps climbing on paper faster than tunnels get dug.
That gap between announcement and execution is the reason to treat Sunday’s post as an opening bid rather than a project. A tunnel spanning roughly 80 miles between two metro areas, running at speeds Boring Company has not demonstrated over any real distance, would dwarf anything the company has built. For now, the Austin to San Antonio Hyperloop exists as a caption under an AI generated space video.

Tesla eyes supply partners for Optimus mass production
Tesla certified three Chinese suppliers for Optimus mass production, signaling its robot timeline is accelerating.
Tesla’s robotics team traveled to Ningbo, in China’s Zhejiang province, on September 16 and spent the following day auditing component suppliers for Optimus, according to a Bloomberg report cited by RobotAIGeek. The visit moved three manufacturers from provisional status to certified mass production partners: Tuopu Group, which handles actuators and chassis components, Ningbo Joyson Electronic, a sensor supplier, and Zhejiang Sanhua Intelligent Controls, which builds thermal management systems. All three already supply parts to Tesla’s electric vehicles, and the audit reportedly came with fresh orders that supply chain reports put at an initial batch of roughly 5,000 units.
Tuopu, Joyson, and Sanhua built their manufacturing base serving the automotive industry, where tolerances and volume requirements are already close to what a mass produced humanoid robot demands. Sanhua in particular has history here. Teslarati reported last October that the company had received a roughly $685 million order for linear actuators tied to Optimus, a volume industry watchers estimated could cover around 180,000 robots once production ramped.
Supply chain reports tied to this week’s audit put Tesla’s near term production goal at about 1,000 Optimus units a week by late September, rising to 2,000 to 2,500 units a week by the end of the year. That pace would put real weight behind the timeline Tesla has been building toward since May, when it wound down Model S and Model X production at Fremont to convert that floor space into a dedicated Optimus line targeting one million units annually. JPMorgan analysts who toured the factory in August confirmed the conversion took roughly four months, a pace Musk has called unprecedented for a facility that size.
New drone video shows Tesla’s Optimus Factory reaching a turning point
Fremont is only the first phase. A second, larger Optimus plant is rising at Gigafactory Texas, where drone footage shared by Joe Tegtmeyer last week showed the structural steel nearing completion on the north end of the building. Tesla has said that facility is meant to eventually support production of up to 10 million units a year, though volume output there is not expected before 2027.
Commercial sales of Optimus are still targeted for the second half of 2027, but production is expected to start well before then. JPMorgan analyst Rajat Gupta has said Tesla’s “Optimus Academy” program, which uses early units to collect real world training data inside Tesla’s own facilities, is expected to be running later this year. Bloomberg Intelligence analyst Ian Ma described the Ningbo audits as “a positive commercialization signal for China’s humanoid supply chain,” noting that sentiment could improve further if the visit leads to confirmed supplier nominations and larger orders. The Solactive China Humanoid Robotics Index rose about 1.4% on the news, though it remains down roughly 30% for the year.

Tesla primes Cybercabs for 4K streaming and high bandwidth gaming with Starlink integration
Tesla is now shipping Cybercabs from Giga Texas with Starlink hardware built in as standard.
Tesla’s Cybercabs are now leaving Gigafactory Texas with Starlink hardware on the rear hatch in significant numbers, according to drone footage captured Tuesday by longtime Austin drone observer Joe Tegtmeyer. Production at the factory ramped back up after the Labor Day weekend, and his flyover of the outbound lot showed rows of gold Cybercabs alongside Model Y Long Wheelbase units, many carrying the satellite module for the first time as standard equipment rather than a one off retrofit.
Giga Texas today is busy with production coming back up following the long weekend. Of interest today in the outbound lot is the appearance of hundreds of Mode; YL’s and many more Cybercabs and for the 1st time equipped with the Starlink module one the hatch in big numbers.

Tesla first showed Starlink built into an actual Cybercab on August 10, when the Robotaxi account posted images of a single gold unit with the antenna integrated into the roofline above the taillights and called it the first Cybercab with Starlink integration. That followed a July reveal where Tesla and Starlink jointly posted a cutaway diagram of the antenna placement without a working vehicle to back it up. Ashok Elluswamy, Tesla’s VP of AI software, said at the time that the connection isn’t required for the car to drive itself. It exists mainly for navigation, customer service and keeping tabs on the fleet.
Musk has made a different case in public. During Tesla’s Q2 earnings call, he said the company can’t afford robotaxis stranded in what he called “Bermuda Triangles of lack of cellular connectivity,” and he separately claimed on X that Starlink will eventually reach every Tesla built, calling it the only way to deliver high bandwidth to billions of vehicles. He has also pitched the antenna as an entertainment upgrade, telling riders they would be able to stream 4K video or play games during a trip.
The rollout has moved fast since. Robotaxi service opened to the public in Austin on September 3, and Cybercabs had already been spotted with Starlink hardware in Houston and near Miami International Airport in the weeks before Tuesday’s factory footage showed the module shipping at volume rather than on scattered test units. Whether the satellite link earns its keep is still an open question. Tesla’s unsupervised service currently runs in dense metro geofences in Texas and Florida, markets where cellular coverage is already strong, which is not where the rural dead zones Musk describes tend to show up.
