Clio 172, Escort RST
I just don't see it I'm afraid. They simply were not different enough from the standard car.
I reckon a few standard ones will be worth a few quid but not crazy values.
As an owner of an FRP I am surprised. You could say the same about an XR3i vs RS Turbo. I know which ones are fetching more :wink:.
As a better example I know which has been worth more over a decade between a Sierra RS500 and a normal 3 door Cosworth :wink:. There's not 'many' differences between those either. Admitedly you did get all of the toys on the RS models.
