Tires, Tires and More Tires
 This was the car I thought I always wanted-500xi with Msport package--what a mistake.This car can not handle a single small road defects without the Goodyear LS2 run flats getting a bubble in the sidewall.I have less than 2500miles and have gone through four tire and two rims.Thisall wheel drive car was not properly tested to handle the roads in the USA. It could do well on the autobahn, but not here. It should not have been marketed with 19 inch wheels and fragile sidewall run flats--what a mistake!Look elsewhere if you want a car that you can actually drive vs on that just looks good in the driveway.
