Verdict
For a Malaysian buyer, the RM181,076 gap is substantial: the BMW Z4 brings 255 hp, 400 Nm and a claimed 5.4-second 0-100 km/h time, while its 280-litre boot is more than twice the Mazda MX-5’s 130 litres. It is also the easier long-distance car with an eight-speed automatic, power memory seats and dual-zone air-con. But the 1,119 kg MX-5 is 372 kg lighter, uses a six-speed manual and costs far less, while adding blind-spot monitoring and front-and-rear autonomous braking. The Z4 is faster and roomier; the Mazda is the sharper value call for manual-roadster buyers.
Pick the BMW Z4 if you want 255 hp, 400 Nm, an eight-speed automatic and a 280-litre boot for regular longer trips.
Pick the Mazda MX-5 if you want a 1,119 kg manual convertible with stronger active-safety equipment for RM181,076 less.
