I can only tell you what my wealthy customers have said, 'cos I'm a gardener and could never afford any of these models...
None of them ever complained about their Beemer.
Audi are what a lot of my customers are driving after becoming dissatisfied with recent Mercs build quality, and their crumby customer service.
Volvos just seem to be having too many complicated electrical problems.
So there you have it!
Get the Audi!
Cheers
