The high performance Vauxhall was built between 1990 and 1992 and features a 3.6-litre, twin-turbocharged engine, with 377bhp. Capable of hitting 60mph from a standstill in 5.1 seconds, and boasting a top speed of 177mph, the supercar rivalling Lotus Carlton is monstrously fast, while its cavernous interior and four-doors make it a practical and usable daily driver. The price of a new Carlton in 1990 was £48,000, similar to that of a new BMW M5, but the recession of the early ‘90s resulted in poor sales and values took a massive dive as soon as cars left the forecourt. In 2008 a good Carlton would set you back £18,000, but over the last 24 months values have slipped further as lack of parts, rocketing fuel prices and the recession have started to squeeze the pockets of enthusiasts. The car uses bespoke parts that wear easily and are very expensive. Brake disks can cost up to £500 each, whereas reconditioned cylinder heads can be over £1000 as well. Furthermore, attempting to source parts is time consuming and fiddly. However, if you don’t mind hunting for pricey spares, and want supercar gratification, the 170+mph Vauxhall could be for you.
