I agree with most of the above. What you forget to say is the the Stupid Wheels come also with Stupid firm and lowered Suspension.
Yes, my second-hand A6 Avant SE came with 20" alloys which thumped loudly over poor surfaces. I couldn't wait to get a nice set of 17" wheels and 55 section tyres on it. The big wheels I will keep because they will add hugely to the desirability/resale value at trade-in time.
My mind is boggled by the number of people who use their cars as an art form. I admit that some of the lowered cars look amazing, but I do wonder how practical they are.
The Germans have got it right. They buy a base car and everything is an extra.
