What in your mind is a proper "RS" then
4x4 - only two RS's have been 4x4 and that can be argued they are basically the same (also rs200 but does that really count for the average joe)
RWD- old escorts a sierra saff and 3 door
FWD - RS1600i, S1/S2 escort turbo, Fiesta turbo, fiesta 1800, escort rs2000, focus RS blah blah
Cosworth - Sierra saff, 3 door and escort cosworth
With all these variations im interested to hear what a true RS is
