BMW’s little roadster is as popular as ever. With its retractable hardtop that can be activated up to 40 km/hr, it adapts to the day’s weather conditions with ease. Unchanged for 2015, its typical roadster lines are reminiscent of the Z3. There’s a choice of three possible engines: a 241-hp turbocharged four-cylinder and two 3.0L six-cylinders developing 300 and 300 horsepower, respectively.
