To me, ANY RS Ford is very special! My two favourites, though, have to be the ones I had the closest contact with, being Allan Moffat's Capri RS3100 Group 2 ETCC factory race car he drove in Sports Sedan racing in the mid-1970s and the mighty RS1800 Escort rally cars driven with such skill by Greg Carr and Colin Bond in the late 1970s. Although they were powered by very different engines, that Cosworth sound was unmistakable - and totally addictive!
