2005 BMW 6 Series 645Ci 2dr Convertible (4.4L 8cyl 6M)
You already know you have overdone it with the electronics. I have 1800 miles on this car and it has been in to the dealership 3 times already. I can't wait for the lease to expire so I can buy a Porsche. Thank god I leased this car and do not own it. Get the idea I'm frustrated? All the problems have been computer related.
The performance, when not in the shop, is fantastic.
Eliminate run flat tires. It doesn't make sense to have a car with no spare. What do I do if I get a flat 300 miles from home on Friday night with no spare? I don't relish the idea of a weekend in a motel.
