THE six-cylinder, 2.8 BMW Z3 convertible has a more aggressive look than the first four-cylinder versions introduced to Australia in January, 1997. Flared wheel arches and a subtly restyled nose fit better with the front of the car while dynamics and equipment levels have been upgraded over the four-cylinder. The Z3 offers levels of ride, handling and steering that readily convey this chop-top is all BMW. Inside, it offers good space for two while ergonomics are up to expected BMW standards.
