I picked up my stealth machine at the end of last year and as it approaches its 2nd birthday and 15k miles (mostly due to me!). I commute 10-12k a year and so far I've been happily using it for my daily drive and don't regret a second of it. I think I've got a keeper, but I can't help thinking that driving something more humble on a daily basis would be better "value" and not cause so much depreciation on the RS4 - again just thinking, not saying I believe it

Here's the question - do I:
(a) reduce the mileage I add to the RS4 by picking up a second runabout, something cheap and cheerful, an A3/A4 1.8T or TDI, for example http://www.pistonheads.com/sales/1179523.htm
(b) keep enjoying the RS4 and just forget about the mileage so long as its healthy
Appreciate any/all thoughts on this....
