Hi, i am planning to purchase a new car, but i have heard a lot of bad things about the reliability of some of the cars that i am thinking of purchasing. I am planning to trade in my only car for either a BMW, Lexus, Acura, or Audi. I have heard only good thing about Lexus, but i have heard that BMW and Audi are very unreliable and that Acura has many minor problems. Have any of you had bad experiences with any of these cars?
