Great 150mph used cars for under £20,000

High-milers start at around £12,000 but we clocked a 2001 car with just 57,000 miles for £19,700. This meant that the 140i would climb through either the six-speed manual or eight-speed automatic box rather rapidly and onto its limited 155mph top speed. Setting off could be a task as the XKR tries to light up its rear tyres with all the 461lb ft of torque on offer but when it is moving it would nail the 0-100mph time in around 10sec and fire onto a limited top speed of 155mph.
