BMW Z3: roadster, coupé and M version, engines
BMW Z3 — a small rear-wheel-drive two-seater sports car produced from 1995 to 2002. Offered as a roadster and coupé, plus a sporty M version. We look at the engines, trims and what to check before buying a used Z3.
Z3 in brief
The Z3 was BMW's first two-seater roadster in many years and the first BMW built in the USA. It features rear-wheel drive, a classic long bonnet and short rear profile, plus a simple, soft removable roof.
On the used market, the Z3 is valued as a cheap and fun old sports car. Prices vary greatly depending on the engine, body style and condition: the M version and coupé command higher prices than standard roadsters.
Which version to choose
The roadster is the classic Z3 shape. The coupé (from 1998) has a fixed roof and a sturdier body, so it drives more precisely, but its body shape isn't to everyone's taste.
The main difference lies in the engine: the simpler four-cylinder units are more economical and cheaper, while the six-cylinder engines are more lively and characterful. The Z3 M is the sportiest version with a powerful six-cylinder engine.
Engines and gearboxes
The Z3 came with four-cylinder 1.8 and 1.9-litre petrol engines (around 115–140 hp) and six-cylinder 2.0, 2.2, 2.8 and 3.0-litre engines (around 150–230 hp). The Z3 M with roughly 320 hp is the most powerful version.
Gearboxes are five or six-speed manual or automatic. The manual box is most prized for driving enjoyment.
What to check when buying a used Z3
The most important thing is the body condition: check for rust on the sills, wheel arches, rear end, and boot, as well as the soft top (for wear, leaks, and dampness). Roadsters are often kept outdoors, so water in the cabin is a common issue.
Check the engine operation, oil leaks, cooling system, clutch, and suspension. Many Z3s were used for spirited driving or modified, so service history and documentation are particularly important.
