Speed is expensive. To make a car go fast you need a big engine, big brakes, uprated suspension components and, well the list goes on. Compare the price difference between a base model and the top performance model in a range and you can often pay up to twice as much for your speed fix.
That is why new performance cars that can really set your hair on fire tend to start at around £40,000. Top tier sports cars will cost many times that amount but thanks to the invisible force of depreciation, a lot of these once pricey speedsters quickly drop in value.
To demonstrate this fact, we have selected some of the very fastest used sports cars that you can buy for under £20,000 and listed their vital statistics such as their performance and what year of manufacture fits our budget. We have also compared them to some new cars that cost the same to see if it really is worth buying used.
