so in the past months I took delivery of my Model S 90D and now have the tesla bug, have always liked the roadster from afar but have stuck with my 911.... now that I have the electric bug i'm thinking about selling the 911 and finding a roadster, been doing some reading on the forum but didn't know if anyone could point me to a good resource as far as identifying the differences year to year and a sort of buying guide... I guess the name of the game is to get the newest one I can find, right? Hear a lot about roadster 3.0... that ever get released as an upgrade and has anyone gotten it? thanks!!
