A 1936 Alvis 3½ Litre SA Sports Special known as ‘Boadicea' has made £46,250 at Dorset Vintage and Classic Auctions on 21 March.
WF 9009 began life as a Mayfair saloon, but by 1973 had fallen into a state of disrepair when it was bought as a rolling chassis by Brian Chant.
Chant set about converting the car into a road-going special eligible for VSCC events and, some two years later, it emerged from restoration as a single-seater with a shortened chassis.
The 3571cc engine was rebuilt by Hunts Engineering of Poole, using an Alvis high-lift camshaft and a lightened flywheel.
Suitably equipped, it competed in numerous circuit races, sprints and hillclimbs.
The Alvis was shipped to America in 1979 where it remained until being repatriated to the UK in 2001, when the car was converted into a two-seater.
A 1949 MG TC also found a new home, selling on the hammer for £20,130. The Midget, which was restored in 1973, had covered just 17,500 miles since and came complete with MoT certificates dating back to 1965, an original brochure and a number of spares.
A 1990 Lotus Esprit Turbo SE, which made £9350, offered much more performance for significantly less outlay.
Completely standard, aside from a custom-built stainless steel exhaust, the supercar was said to be in generally good condition apart from some minor defects to the bootlid and came with a large history file.
