It appears to be the colour scheme rather than the car (except when it comes to the R19).
Personally I liked the Group A rovers and whilst Soper's wasn't the prettiest it did win the championship, only to have it taken away again on appeal.
Based on the fact that the BTCC or British Saloon Car Championship as it was known, goes back some years, I'm surprised nobody's mentioned the Masaerati from 83, or the Ford Falcon from '64.
I liked the Mondeos in facelift form but the Renault Laguna in any colour just ain't my particular cup of rosy.
