Most Porsche 928s were built to be cruisers, but the 1990 Porsche 928 GT now live on Collecting Cars was built to be driven. The GT came only with a manual gearbox, sport seats and a firmer suspension, and this Marine Blue example is sitting at £8,205 with 27 bids and roughly three days left.
What made the 928 GT different
Porsche introduced the GT for the 1989 model year as the enthusiast's 928. Where the S4 was the plush, automatic‑friendly grand tourer, the GT was manual‑only, using a dogleg five‑speed with a shorter shift lever. Its 5.0‑liter V8 is quoted at 326 to 330 horsepower depending on the source, it rode on a more aggressive suspension, and Porsche trimmed equipment to save weight, placing it between the SE and the S4 in specification.
The differential is the other quiet detail. The 1989 cars had a ZF 40 percent limited‑slip unit, and from 1990 an electronically controlled variable‑ratio unit, Porsche's PSD, became standard on the GT. A 1990 car like this one should therefore have the newer system, though the seller says this one is not currently working.
This car's specification
The seller says this UK‑market car was first registered in February 1990 and describes the factory‑fit sport seats for driver and passenger, sport shock absorbers, impact‑absorbing bumpers and an electric sunroof. It is finished in Marine Blue over a Linen and Marine Blue leather interior. The odometer shows 116,893 miles, which the seller believes is genuine.
The listing says just 225 GTs were sold in the UK. Worldwide figures vary by source, and Porsche reportedly planned only about 100 GTs for the United States in 1991, so any GT is uncommon even if the exact total is debated.
What bidders should know
This is not a flawless example, and the listing is upfront about it. The seller notes that the Porsche Sports Differential is currently non‑functional, with a possible solenoid fault, along with some loose stitching on the steering wheel and minor stone chips on the front bumper. The car wears 17‑inch Cup II wheels, while period references describe the GT's standard wheels as 16‑inch designs, and it has a Strosek rear wing, so buyers should ask questions in the comments about what is original. On the positive side, clutch master and slave cylinders were replaced in May 2026, and the car came with a stamped service booklet, manuals and invoices.
Why it matters
Transaxle Porsches have long been the value alternative to the 911, as Motorious has covered with an ultra‑low‑mileage 924S. Enthusiasts who prefer a manual will appreciate that the GT gave Porsche's V8 grand tourer a stick and a sharper chassis, much like the manual 911s we've featured, including a 996 Carrera 4S Cabriolet with the factory X51 Power Kit. At the current bid, a manual 928 GT is a lot of V8 grand tourer for the money, provided you budget for the differential.
