1989 Porsche 928 S4

This lot will be auctioned via Iconic Auctioneers, The Classic Sale at CarFest 2026 on Saturday the 29th of August and Sunday the 30th of August at The Wing, Silverstone Circuit, NN12 8TN.

The S4 was launched in 1987 with smoothed-off bumpers, a larger rear spoiler, more interior equipment, and a 5-litre, 32-valve version of the V8 engine developing 330bhp.

UK-supplied and first registered on 10 March 1989, this Grand Prix White example with an automatic gearbox is offered from nine years of current ownership.

Our vendor advises that the car was purchased in 2017 from an RAC patrol engineer and was running well at that time. It was subsequently entrusted to a Porsche specialist for servicing and investigation of an ignition coil issue before being placed into storage around the COVID period.

We understand that the specialist passed away during the COVID period, and it is not known what work, if any, was completed.

The vendor further advises that the car has not been started since approximately 2018 or 2019 and should not be started until fully recommissioned. The air filter and ignition coil have been removed. The car rolls freely but is offered strictly as a non-runner and will require collection by trailer.

The odometer was indicating 135,856 miles when the most recent MOT test was carried out on 17 May 2017. Interested parties are strongly encouraged to inspect the vehicle in person at the auction to assess its condition and the scope of any work required.
