1) what warranty is this, I don't get it if you got a warranty thru BMW or some aftermarket. Since your already 2k over the oem warranty, I'm guessing the dealer gave you some aftermarket warranty that they do business with.
2) what are the specifics of your current warranty. Deductibles, coverage, new or refurbished parts, what repair shops.
BMW and Mercedes Build Beta Products!
Lexus build Release Candidate Products!
Why does this matter?
CAUSE EVERY TIME someone says Lexus has better build quality, one should consider what Toyota their Lexus Engine and chassis platform comes out of and how long that part has been tested in the real world!
