Condition
9
The car is described as 'Genuine, Highly Original RS' with over 20 years of ownership. It has been used sparingly, primarily for shows and events, and kept to a very high standard. It is a genuine, standard and unmodified example that has never been rebuilt or repainted. While it has a performance chip and stainless-steel exhaust fitted by Collins Performance, and was professionally detailed underneath several years ago, these are minor deviations from original specification. It has spent several years stored off the road in a Carcoon and is currently kept in a storage tent. It is a former RS Owners Gold Cup winner and has enjoyed multiple show wins, and has been displayed at major shows. There is an extensive history file with years of service, maintenance, and rolling-road documentation, including specialist work like a refurbished turbo, replaced head gasket, full suspension overhaul, and rolling-road tuning. This indicates a well-preserved car with an excellent history and specialist maintenance, showing minor signs of use consistent with a rating of 9 (Outstanding).
