The only significant repairs I can imagine on this vehicle are replacing the tires or brakes. As long as the oil changes and maintenance are done regularly, I highly doubt the engine will have any problems until 200,000 miles or so, at which point the vehicle will be almost 20 years old and have cost about $1,000 a year to drive.
New vehicles are incredibly reliable (compared to vehicles produced in the 20th century) and are likely to last a long time, although the electronics will surely be dated when they are 20 years old.
The tesla vehicles have an 8 year warranty on the battery pack, which is the only item besides tires, brakes, and windshield wiper blades that is likely to wear out.
This is Tesla marketing through and through. Look at all the problems the Model S owners have had and reconsider the statement.
I expect it to be a great car but I see people looking at it who really aren't in a position to do so.
Repairing this thing out of warranty will be even more of a joke than with regular new cars (and that's already an economic tragedy.)
