BMW replaced the Z3 with the Z4 in 2003, initially offering only a two-seat roadster body style. The hard-edged styling was controversial at the time, but over the years consumers have come to accept it. The styling was mildly updated in 2006, when BMW introduced new engine choices, a sensuous hatchback coupe, and a high-performance M model. The Z4 carried over virtually unchanged for 2007.

With only two seats, rear-wheel drive, and a base price in excess of $36K, the 2007 BMW Z4 isn't a practical family car. It's better thought of as a second car. But, oh, what a second car it is.

Most of all, the Z4 is a blast to drive. The engines provide smooth, ample power. Coupe or roadster, the BMW Z4 offers sharp handling that is the match for anything on the road, yet the ride is compliant in base models. The interior is comfortable and well-assembled.

The high-performance M Coupe and M Roadster versions of the Z4 boast better handling, but can become harsh on rough roads when equipped with the optional Sport package.
