Trade audi S4 for an E39 M5
I never drove an BMW M5 E39, but was always interested into buying one.
I currently own an 04 Audi S4 B6 (V8 engine) and like the car, but maybe looking to trade it for the M5.
The M5 would obviously be a little older and with a little more mileage.
The S4 has quattro, but since I won't drive both car in the winter, this is not a major plus for me.
What do you think about this? Would you do the trade?
