I decided to sell my MPV just 5 years after I bought it because it was rusting so badly at the base of both the passenger and driver doors as well as on all 4 wheel wells. In this day and age you don't expect a vehicle to rust before it's even 10 years old and this car began rusting when it was just 3 years old. When I brought the problem up to Mazda they were only willing to go by the book: The rust warranty only kicks in when the rust has perforated the metal. Well it's perforated now--now that the warranty has expired. Between fixing the rust and some other scheduled maintenance I was going to be spending more on the car than it was worth. So I cut my losses and sold the car.
