The M version of the E46 arrived in 2001, its 3.2-litre straight-six featuring an evolution of the 330Ci’s Double Vanos variable valve timing, while a lightweight crankshaft and graphite-coated aluminium pistons allowed it to spin at 8000rpm. In 2003, the £58K CSL brought 355bhp, a carbonfibre roof, cut-slick tyres and a price tag £20K over the basic car. The halfway-house CS of 2005 was an evo favourite.

It’s scarcely believable that E46 M3s can be as little as six grand, but obviously be cautious at that price. From £7K there’s a huge choice, and £10K buys a very good car.
Good servicing is crucial, including the run-in service at 1200 miles – the cheaper the car, the more likely that corners have been cut. Pre-June ’03 engines were prone to crankshaft big-end bearing failure; oil supply upgrades should have been sorted under warranty. The 19in alloys are easily kerbed, and repairs are costly. Uprated brakes are a boost for trackday users. Find out more at m3cutters.co.uk
