The S4 is a very rare car. When production of the S ceased, the V8S made up most of the sales. Given that the V8S was £5000 more than the V6, most buyers were going for the extra performance offered by the larger engine. Opinions vary with somewhere between 32 and 49 cars thought to have been made, with at least 3 in left hand drive.
The S4 is basically a V8S but with the V6 engine. It’s got the strengthed, wider track chassis and all-round disc brakes of the V8S, but has a bonnet without the hump. Other minor detail changes are the inclusion of the nicer looking roof stays from the Griffith, the relocating of the battery to the boot, and different wing mirrors.
