Hello Roadster owners and fans. I am ready to purchase either the roadster (1st choice) or a used Model S. I am looking for advice from the people that drive these awesome vehicles. My biggest concern: is the roadster going to be reliable for a daily driver? I am coming from a Leaf so range isn't an issue - I only drive about 30 to 40 miles a day, average. 2nd concern: how difficult or expensive is the car with maintenance. I'm in the DC metro area so close enough to Tesla service locations. 3rd, and most important, depending on answers to 1 and 2 - anyone looking to sell a 2010 or newer roadster in the $50k range? Thank you!
