When the RS500s were racing in the late eighties/early nineties there were two well known rivals: Andy Rouse and Rudy Eggenberger.
The Eggenberger cars were distinctively well dressed, being black with red Texaco livery, whilst Rouses Cosworths were typically blue and white.
Eggenberger kept his cars immaculate, and was backed by Ford. Even under the bonnet, they were pristine before and after every race. Rouses cars weren't so 'bufty', but were equally impressive. Rouses cars may have been a little grubby and battle scarred, but still went like stink and as long as they stayed in front, that didn't matter.

So, the question is, are you a Rouse student or an Eggenberger one?
