That kind of surprises me as my experiences are quite the opposite. My current 8V is the eighth Audi I've owned. In between, I've had VW and Toyota. In fact, I felt the quality of materials was poorer in the Toyota but reliability was second to none. Build quality was poorer in the VW even though components were largely the same. The very thing that put me off both BMW and Mercedes was that the quality wasn't as good as Audi. Buying new, I quite like the fact they're over-engineered. I wouldn't have one outside of warranty any more solely because of the cost of repairing them but poor quality components is something I've never associated with the Audi brand.
