You don't say where you are, Watty, so I don't know if you would want LHD or RHD.
Originally there were 151 saloon Rover 75 V8's made, of which 35 were LHD (including mine!)
There were also 16 Tourers made of which only 3 were LHD.
The list of cars for sale here on the Forum is updated 2x daily, and currently shows 2 Saloons for sale in the UK (RHD), 1 in Australia (RHD), 2 in Holland (1 LHD, 1 RHD) and 1 in France (LHD). At present no Tourers are known to be for sale.
