About the BMW M Roadster
Produced from 1998 to 2002, the BMW M Roadster (E36/7 and E36/8) featured the 3.2-litre S50 or S54 straight-six engine producing 240-325bhp depending on specification. The UK market received both the earlier S50B32 engine (1998-2000) and the more powerful S54B32 (2001-2002). With its distinctive 'clown shoe' silhouette when in coupe form, the M Roadster offered genuine supercar performance with 0-60mph in under 5.5 seconds. Production numbers were limited, with only around 15,000 M Roadsters built globally, making it a collector's item today.
What Affects the Price
Engine specification is the primary price determinant, with S54-powered models (2001-2002) commanding a £5,000-£10,000 premium over earlier S50 versions due to increased power and desirability. Mileage significantly impacts value, with sub-50,000-mile examples fetching top prices whilst cars exceeding 100,000 miles trade at notable discounts. Condition and service history are critical; comprehensive BMW specialist maintenance records add substantial value, as does evidence of major maintenance like VANOS units, cooling systems and rear subframe reinforcement. Original paint, unmolested interiors and matching numbers cars achieve premium pricing. Colour combinations matter, with Estoril Blue, Imola Red and rarer shades commanding more than silver or black examples.
Buying Tips
Inspect the rear subframe for cracks or previous reinforcement work—a common issue on E36-based models that can be expensive to rectify properly. Check for smooth VANOS operation with no rattling on cold starts; rebuilds cost £800-£1,500. Examine cooling system components including radiator, water pump and expansion tank, as failures can cause head gasket damage. Verify the convertible roof mechanism operates smoothly with no tears in the fabric. Insist on evidence of regular oil changes using BMW-approved oils, as the S50 and S54 engines are sensitive to maintenance quality. Check for any rear differential whine and gearbox synchromesh issues, particularly on second gear. Look for corrosion around wheel arches, sills and windscreen surrounds. Consider a pre-purchase inspection from a BMW M specialist—these cars are now appreciating classics and warrant professional scrutiny before purchase.
