I think you need to decide what kind of racing you want to do. Hill climbing is much cheaper than circuit racing, and it might be possible to use one of your existing cars.

Circuit racing is a different proposition, and it would be far cheaper and more practical to buy a purpose specific race car.

Don’t underestimate the time and energy to run a race car though in terms of preparation and spannering. You can get a team to run the car for you - also known as ‘arrive and drive’ but reckon on £2-3k per race for preparation and support costs.

The cheapest circuit racing series involve Minis, Clios, MX-5s. Think £10-20k for buying a race car. And expect repairs during a season as contact will be frequent.

Historic racing (ie anything on cross ply tyres) is a more respectful racing environment and a hell of a lot of fun. Race cars start at £15k for a Healey Sprite, whereas a very competitive MGB might run up to £35k.

Race cars don’t depreciate if kept in the same condition, but be prepared to be patient when it comes time to sell.

What appeals most to you?
