I've just moved jobs and my new company also has a Fleet Department where company cars are 'encouraged' so the RS is going

I've looked on Audi and Pistonheads and struggling to set on a price. Similar cars through a dealer are circa £40 - £42k so presumably with a profit margin of £5k I'd be looking at a dealer sale of between £35 - £37k with a slightly higher figure for a private sale ??
Your thoughts / advice / offers would be appreciated.
Cheers
Rich
