2007 BMW Z4 M

A 2007 BMW Z4 M Roadster finished in black, powered by the naturally aspirated 3.2-litre S54 straight-six shared with the E46 M3 CSL — an engine that remains one of BMW M's most celebrated units. Showing 36,422 miles with three prior keepers, this example comes with a useful factory options list including SatNav Professional, heated seats, folding exterior mirrors and black carbon-structure leather trim.

The Z4 M Roadster is increasingly recognised as an under-the-radar modern classic: short production run, hydraulic steering, a six-speed manual gearbox and the last pre-turbo M straight-six. Values for well-kept cars have been firming, and finding one with sensible ownership history and documented specification is becoming harder. A tidy entry point into analogue M car ownership.
