1991 Ford Sierra RS Cosworth 4x4 Rouse Sport 304R

Highlights

• One of approximately 78 Rouse Sport 304R examples produced from a planned run of 100
• Only two former registered keepers from new
• Supplied new to the wife of the supplying dealer's owner, with original dealer stickers and number plates retained
• Accompanied by a letter from Andrew Rouse, stamped service book, and extensive history file
• Cambelt replaced in May 2025, with further maintenance carried out in May 2026
• MOT valid until May 2027

The Appeal

Developed by BTCC legend Andy Rouse in conjunction with the Ford Motor Company, the 304R package elevated the already formidable RS Cosworth 4x4 with an uprated Garrett turbocharger, remapped ECU, reworked induction and exhaust systems, an aerodynamic bodykit, and Rouse-branded Recaro seats. With only around 78 examples believed to have been produced from a planned run of 100, these are genuinely rare machines.

This Moondust Silver example benefits from a clear and traceable history. Supplied new by Grays Ford of Guildford to Mary Gray, wife of the dealership owner, it retains its original supplying dealer stickers and number plates. The car is accompanied by a letter from Andrew Rouse himself, and the stamped service book records regular servicing from new, predominantly carried out by the supplying dealer.
These vanishingly rare Sierras are an exciting prospect, and we're sure this one will garner plenty of interest at auction.
