Service is easy since it'll be under warranty..Cost is near zero..I think the only thing you pay for is tires...Everything else is covered I believe...As far as 10 years goes...Well, I'd say if you maintain it it has a good chance of being relaible. Technology has gotten better these days so hopefully it'll last..But I personally don't like to keep cars longer then 7 - 8 years at the most, Bimmers especially, as there is usually something newer that I want!
