Auction Sales History

1958 Austin-Healey 100/6 BN6L/3814 –

This BN6 two-seater was imported from Arkansas, USA in 1990 and then converted to right-hand drive. Its first owner in the UK was a Mr Brian O’Connell (see purchase invoice on file). The current vendor purchased the car in 2001 and carried out a full restoration to a very high standard during 2004/2005. This ‘last nut and bolt’ restoration included an engine rebuild (cylinders re-bored, crankshaft re-ground, new pistons, crankshaft and flywheel balanced, pro/race damper fitted, etc); oil cooler fitted; disc brakes serviced; brake servo fitted; gearbox overhauled and overdrive fitted together with a new clutch; new all leather upholstery; new high grade bespoke carpets; bespoke mohair hood and tonneau cover; four new 60-spoke chromed wire wheels; and a stainless steel exhaust.
