Hi DrRick. Last year I traded my 2001 X5 4.4 for a 2013 X5 3.5. I hear what you're saying about the quality. BMW over engineered the first model because they couldn't afford a bad introductory review. In the next models they engineered out some of the complexity and details to keep the weight and cost down. All things considered I find the E70 a better ride in every way than the E53. Though some may argue the E53 is better looking. The midwest and east with their rough winters and salted roads are tough on vehicles though. Good luck with your new ride.
