I'm in California right now and have gone through my share of cars down here. There's no worries about rust down here, but a lot of cars are salvage and are not garaged, leading to wear from the sun.
I'm looking to grab a Z4 but I've no idea what the service schedule for them is.
I've heard at 150k km, alot of these cars require a new starter, alternator and lower control arm bushings. Is there anythign else to look out for? Are the doors on a 2003 Z4 supposed to have a slightly harsher knock/close than any of 5 or 3 series? I noticed this on a Z4 I recently test drove.
The cars that I'm looking at are in the 65k to 90k mile range (110k km to 150k km). Manual, of course. There aren't many 3.0s down here, unfortunately.
Edit: One of the Z's I'm looking at has a bent front fender from an apparant previous previous owner who "let the car slip on the jack" and caused the jack to hit the fender, giving it a dent on the bottom. How much does it cost to get a Z4 front fender part and have it painted?
