That's one thing I really liked about the first Honda Insight (lightweight two-seater hatchback hybrid - looks like a space egg). Picked one up last year for dirt cheap because I have a long commute. Got 70 mpg (mostly freeway). Great thing was I could also work on it pretty easily. Even worked fine without the hybrid system (they're all old enough where the batteries are crapping out) So sad when another car totaled it.
That's when I will probally buy one. I was just thing about this the other day. I was thinking when they get to the used market, and guys start modifying them; that's the day I'll put on my dielectric gloves and put that charging station in my garage.
Right now, a vechicle I can't modify, and work on is just not my style. If I had disposable income, it would probally be a different story.
Exactly why I'm hesitant to buy one. I mean, I was paranoid enough when buying my Macbook Pro (omg, it's all soldered!), so a Tesla is probably not for me in the long run.
I would gladly lease one though, but it seems impossible here in Denmark.
