 Had a 318i for 7 years- never a problem with repairs, etc. Only got rid of it because it had 100,000+ miles on it and was worried it might start breaking down. Bought the Z3 as a preowned vehicle - with warranty. Have had it in shop countless times, last time being it needed a new radiator - have had lots of repair issues, it is now just out of warranty and I am hoping it will not break down any more. Love the car, it's cute and fun but disappointed in repairs so far. Other BMWs superior to this one :(
