I've been doing some research about high mileage Roadsters as I'd like to know how well they have held up. So far the highest mileage Roadster I've found mentioned online was at http://www.teslamotors.com/blog/northern-california-roadster-record with roughly 67,000 miles back in mid April. The article doesn't say much about how reliable the car has been, but I wouldn't take it into consideration anyway cause it is "Validation Prototype 11". Does anybody else have over 50,000 miles on their Roadster? If so, have you had any major problems? I've read that the battery pack loses %30 of it's capacity after about 50,000 miles. Has anybody personally verified this? Thank you in advance for your responses!
