The's another post on the Tesla forum. Kelly Blue Book value for a 2014 P85D is $76,051 with 15,000 miles. Nada shows $78,000. Tesla's trade in offer was $82,000. If this dealer paid blue book value for the car and then sold it for $87,000, they did pretty darn good on it with a $9,000 profit.
Performance models where people pay $20,000 literally for JUST A MOTOR upgrade that likely doesn't cost Tesla more than $2,000 are taking a huge hit when it comes to how companies, including Tesla, value the cars. People pay that price because the can and they want the best of the best. $20,000 is however stupid money for such a small difference in mechanical parts. Not knocking it, I paid it too. But generally, the higher the price a car is, the more depreciation it will have. Performance models across any brand, almost always show significantly higher depreciation rates than the base models of the same car.
Everyone says it was steal, but there are 4 or 5 other P85D's on E-bay that are listed around $100,000 and they've been on there for quite some time. That means people aren't willing to pay that much for a year old car. $87,000 might be a tad on the low side, but it was an auction and that's what it got bid up to. No better indicator of "market value" than the E-bay system. It tells you what people are willing to pay for it. Other's certainly could have bid more, but didn't.
There's a reason KBB, NADA and Tesla only pay 57% to 61% for year old P85D's.
