With an overall length of 4,025mm and wheelbase of 2,459mm, the Z3 M Coupe is fairly stubby but it still manages to offer a 300-litre boot. However, taller drivers will find the driving position cramped, not helped by the limited adjustment in the steering column. Some also complain the leather seats, though finished to a very high standard and hard wearing, lack support for shoulders and thighs.
Some owners fit aftermarket seats to gain more headroom and comfort, but make sure any potential purchase has the original seats included. The standard seats can become loose on their mountings as the bushes in the mounts wear. It's quick, cheap and easy to fix. It's also not unusual to find a previous owner has swapped the original steering wheel, which is lifted from the E36 M3 Coupe, for a smaller wheel. This is an accepted upgrade for the M Coupe, but it does mean losing the driver's airbag.
Side airbags were a £275 option and worth having. Other options for the cabin included cruise control (£275), uprated CD stereo (£175) or a Harmon Kardon hi-fi (£585), and CD autochanger £495.
Air conditioning was supplied as standard, along with the leather upholstery in black or two-tone finishes, and chrome bezels around the main instruments. There was also chrome detailing for the three centre console-mounted dials and the gear lever gaiter. All UK-spec Z3 M Coupes come with a 170mph speedo dial. The gear lever had an illuminated knob and the light inside is prone to failing.
