Ultima RS

The Ultima RS is a British-built, spaceframe road-and-track car that pairs a roughly 930kg kerb weight with a big American V8 and no driver aids. This 2023 example uses Chevrolet's supercharged 6.2-litre LT5, rated at 755bhp, driving the rear wheels through a Porsche six-speed manual transaxle. The quoted figures are 0-60mph in 2.3 seconds and a gearing-limited top speed beyond 250mph.

It was assembled by Tony Castle-Miller of Middle Barton Garage between April 2022 and August 2023, with around £45,000 spent on labour. The spec includes a full carbon aero package with a 1780mm double-element rear wing, Nitron adjustable dampers, 362mm discs with six-piston callipers, a hydraulic front lift system and forged 19-inch wheels on Michelin Pilot Sport 4S tyres. The body is white, with leather seats and an Alcantara dashboard.

It has one owner and shows just 50 miles. The car is currently unregistered, though the dealer states it is road legal and can be registered as it stands. A nearly new PRG Prosporta Monza twin-axle enclosed trailer is included in the sale. The car is shown as under offer.
