I was at one of the Tesla showrooms and asked about the yearly maintenance. I was told it was going to be $600/year. I remember reading somewhere that it was included in the first 4 years or 50K. Does anyone have any confirmation of what the exact cost is? I also asked about leasing and was told that it should be announced this year and would be done by Tesla. Any other information on this? Lastly, based on the Tesla Roadster, in 5 or 6 years, what percentage of the price would you think the car would be worth? 30/40/50? My hope would be 40. Any guesstimates on this? Thanks.
