I am in the process of purchasing a roadster... Since hindsight is 20-20 I thought I would ask the experts in this forum, what you would do differently if you could travel back in time to the beginning of your journey with Tesla Motors. Are there any specifics that are important to get covered early on in the sales process? Any gotchas (particularly since I am in Europe)? What's the room for negotiation in terms of pricing? I would be very grateful for any tips that you could spare, since this is definitely new territory for me. Maybe a resulting "purchasing checklist" may be helpful to other newbies in the community as well. Thanks a lot for your help.
