Hi I've just started looking at S5's
What sort of money would I be looking for a 50k late 08 S5 private sale?
Thanks in advance

Oh right is that what they are actually selling for as they don't book anywhere near that?
I had a look on autotrader this morning there are a couple round the 15k mark with full audi history
