I am not sure how you have up with $52k.
By my model :
$118,000
- $7,500
_______________
$110,500
30k miles = 30% depreciation = $33,150
5% drive off penalty = $5,525
Car Value = $110,500 - $33,150 - $5,525 = $71,825
Yobigd20's calculations are:
$103,000 - $7500 (tax credit) - $8240 (1% per month depreciation) - $33,150 (mileage depreciation) = $54,110
If you put on 30k miles in 8 months, you bet your car has depreciated really really bad. Your warranty is just about up. At your rate, warranty will be out in another 5 months.
Tesla will use the "original purchase price" for their calculations and not the "current MSRP". I assume that because when I got Roadster's trade in value, they used the original 2009 purchase price not the latest 2011 model price. Which makes sense because who knows what the "current car" has for options and design changes.
correct, I started from the $103k number and just did a rough estimate without using calc. so that $$ sounds about right. assuming I drive 50k a year, basically this means my $103k (or $118k, however you want to look at it) car is worth $0 in about 18-19 months? I don't think so.
My model comes up with $71,825, and honestly, with 30,000 miles on your car, that is a pretty fair price. Most 8 month old cars will have less than 10,000 miles on them. To reach 30,000 in such a short time, one would have to assume that you have likely used almost an entire battery cycle every day, and would most likely have taken frequent advantage of the supercharger network. Using the battery in this way has the potential to significantly increase the rate capacity degradation. (note, you may not have done this, or that your car has suffered any range decay, but without any details one way or another, most buyers will make this assumption).
I just ranged charged last weekend to 265 rated range. I have seen NO degradation. I do a little over two half cycles daily. 80%->~35%->80%->35% etc. I have never supercharged. Once of those half cycles is on a NEMA 14-50 set to 25amps and the other is on a Chargepoint pulling 30amps. This is consistent 5 days/week plus a few shallow charges cycles on the weekends. In total I have probably ranged charged about 5 times total including last weekend. IMO this battery could last a VERY VERY long time. Mileage doesn't seem to affect rated range degradation. I would have expected to see a few miles lost by now but I have seen none.
