The car has been bought-from and serviced by the selling main dealer and owned by an older woman who's business also had an RS6, R8 etc. In fact, the registration plate was possibly worth more than the new price of the car!
I've test-driven it and it felt brand new.
I've read through the forums here and seen the scare stories about DRC and oil use. Is there anything I should specifically be looking for once I get the car???
