I am interested in acquiring a Tesla Roadster, for use both as a PR/Marketing tool & Development work (PEM/drivetrain & transmission). There is also the question of turnaround time. What are the trade-offs between models (2008, 2009, 2010, regular or Sport) & delivery times? Is the Sport worth the extra cost? What are the current delivery times like? Or, should I try to get one used, like from Ebay? I am in Los Angeles area, I would prefer a California car (no rust).
