There was'nt such a thing as a factory 385bhp upgrade. He's probably referrring to the Nothelle upgrade which was marketted in the UK by Scotts.
Condition wise the car looks ok but the lower door plastic trims are coming lose and the passenger door looks misaligned.
Given that there are now only 80-90 RHD examples left of the RS2 prices might begin to firm up and possibly increase for well cared for examples.
FYI, New Zealand has about 15+ RHD RS2's. Not bad for the population size of 3.5 million. PS Australia got Zero, as they handed over their allocation to NZ. Obviously we have lots of petrol heads with coin.
