BMW Z4

£28,535 - £43,970

Z4 irritates the purists by getting a folding hard-top. Engineers around the world are currently burning effigies of whoever thought that was a good idea, while the fashionistas are burning incense.

Still not as great as a Porsche Boxster, but getting closer with every generation. New folding hard-top gives it the predictabilly slightly fat arse, but otherwise it looks as good as any other hard-top.
