Tricky
You wouldn't go with S5 A5 RS5 as they don't handle well.
I remember from last conversation RS6 being the ultimate car and right size, but you won't go the same now.
Therefore not S4 or RS4 unless you going through middle life crisis as this is more boys car and mans car.
I can't see you driving any Q
A6 Bi-Turbo TDi you said to expensive range therefore it won't be newer RS6 or RS7.
There are only two previous cars which you would drive again, I think, and one of them being newer model, I can only narrow it down to two cars:
- A7 or even S7 as you liked it very much
- or D4 A8 TDi which you will remap and do an economic monster from it.
50/50 between them two cars
