I’m just ordering the ENYAQ IV 80x. One thing I’d like to claim is your help. Standard are the 8J x 19″ “PROTEUS” light alloy wheels. I was advised to take the 20″ “VEGA” light alloy wheels, silver. My car is Brilliant Silver, Metallic. Now the question: What is the advantage of the 20″ wheels? Is this purely optical or is there any technical differences in driving behaviour?
