A FORD Sierra RS500 Cosworth built by Eggenberger Motorsport has come onto the market after a “no expense spared” restoration.

The legendary Swiss touring car squad is best remembered for fielding the black and red Texaco-backed works cars and only built a handful of brand new cars for customers.

Two such cars went to Allan Moffat in 1988 and 1989, becoming the ANZ and then Cenovis-backed cars that claimed a Shootout win and a pole at the Bathurst 1000 in the hands of Klaus Niedzwiedz.

The car that is up for sale is another customer car, built for the Trampio Toyo Tyres team to race in the All-Japan Touring Car Championship in 1988.

In a parallel with Moffat, the Trampio team had initially bought a Sierra from Andy Rouse in late 1987 but, after encountering reliability issues early in the 1988 JTCC, replaced it with this Eggenberger car!

The car secured the 1988 JTCC title for driver Hisashi Yokoshima, who paired with Niedzwiedz to win the Inter-tec 500km final round at Fuji.

The achievement was commemorated by a 1:24-scale model kit produced by Tamiya, which made the car’s distinctive Ciesse Piumini livery famous worldwide!

According to the listing on racecarsdirect, the Trampio team continued to race the Eggenberger car through 1989 and 1990 and was run briefly by a new owner in 1991 before being sold to a collector in Japan.

The car was subsequently sold to a collector in Singapore and then England, before being purchased by Vink Motorsport in the Netherlands in 2017 which has just completed a full restoration on the car.

The original Eggenberger engine remains with the car, while all the panels bar the left-hand door are also original, plus the car comes with a large package of spares from the original stock supplied with the car by Eggenberger.
