1999 BMW Z3M Roadster

Launched in 1997 and only in production for five years, the Z3M Roadster was developed by BMW's M-Sports division who installed the magnificent 321bhp, 3.2-litre straight-six engine from the contemporary E36 M3 Coupé, along with that car's beefed-up suspension, limited-slip differential, brakes and 5-speed manual gearbox. The package was topped off with massive alloy wheels, quad exhausts, and a more aggressive front spoiler and side skirts. There were also interior upgrades with additional gauges in the centre console, M-Sport gear knob, various chrome bits throughout the cockpit and leather sport seats as standard equipment. The result was a proper sports car that could scorch to 60mph in 5.2 seconds on its way to a top speed limited to 155mph. Only 15,375 were built in total but of these only 3,557 were to full power European spec (American cars only had 240bhp) and only 997 were right-hand drive.

However, it wasn't until 1999, when BMW installed the performance version of one of the most beloved six-cylinder engines in the car industry, the 3.2-version of the S50 engine from the E36 M3, giving 316bhp at 7,400rpm and 260lb/ft of torque, that the Z3 became an interesting driver's car. It could now sprint to 60mph in 5.2 seconds and on to a maximum speed of 155mph, aided by uprated suspension, an LSD, a wider track, and larger brakes, all combining to create a proper sports car experience. Today, these cars possess a real feeling of integrity and a distinctive old-school charm; UK's Top Gear declared it "'the best handling car in the business."

Finished in Estoril Blue over a black leather interior, this lovely example was specified from new with a healthy collection of added extras including air-conditioning, a Harmon Kardon sound system and sports seats. Fastidiously maintained, the Z3M comes with all of its original paperwork, booklets, brochures and even the seldom seen Z3 wristwatch, one of just 5,000 made specifically to go with the Z3M Roadster. Despite only covering 19,826 miles, this example has been exceptionally well looked after, living its whole life in a temperature-controlled garage and undercovers. The service booklet has been stamped by main dealers and specialists up to 17,700 miles.

With the prices of effectively any and all pre-2000 M-Division cars soaring through the roof, this somewhat overlooked M3 powered 'pocket rocket' is surely the best and the sneakiest way in to that club!
