As custom ordered new Roadsters are no longer being offered for sale in USA, people are starting to look harder at used ones as they become available. A few people contacted me asking if I could give advice, but I don't have a whole lot to say about it. You can watch eBay and Craigslist and sometimes find them there. You can just Google for Tesla and sometimes find that someone traded one it at a car dealership which then offers it for sale. I have no idea if the sales reps at the Tesla stores will be helping to locate used Roadsters or not. In terms of what Roadster someone might want... I think generally newer is better as "improvements" were made during production. Also, the battery packs slowly age even if not used, so a newer pack is generally better. The later years had among other things: More comfortable seats. More sound proofing (quieter ride). Better dashboard (kWh gauge instead of pointless tachometer.) A small glove box was added and the dashboard was more covered in leather. Double DIN radio for better GPS/Nav option. Optional carbon fiber accents. Optional black wheels. 2010 got rid of the "stick shift" gear selector and put buttons in the center. The VDS screen also moved from the left knee position to the center in front of the shift buttons. They basically fall into these buckets: 2008 Model 1.5 (VINs 1 through 500) 2010 Model 2.0 (VINs 501 through 963) 2010 Model 2.5 (VINs ~964 through 1169) 2011 Model 2.5 (VINs 1170 through 1464) Also, the 2.x models could be ordered as a "Sport" with 0-60 in 3.7 (instead of 3.9), adjustable suspension, (in some cases) performance tires, and such. I would say that the Sport variant would carry a premium over the non-sport. There are various options that could be added the car that would affect resale value. I won't try to list them all or project what they might be worth, but a few majors ones would be: Hard top HPC (high power home charging station) UMC (Universal Mobile Charger) MC240 (precursor to the UMC) Note, among the first Roadsters made were the "Signature 100" series. These may have special plaques (between the seats) with signatures of the team that worked on the Roadster, and in some cases the original buyers name. Also, they offered a special color "Signature Green" which wasn't made available anymore after the first 100.
