The Mazda MX-5 is the cheapest sports car you can buy. Prices start from around £25,000 for the 1.5-litre version in SE-L trim, rising to £31,000 for the 2.0-litre GT Sport Tech. You’ll pay around £1,500 more for the entry-level RF (Retractable Fastback) version, which features a folding metal hard-top. The all-new Toyota GR86 is likely to cost around £30,000 when it goes on sale in mid-2022. Power is sourced from a 2.4-litre flat-four Subaru engine.
