BMW Z4

The ride quality is far better than it was on the old car, but then that was the general idea from BMW. They wanted this one to be less hardcore. So the optional electronically controlled dampers do a better job of keeping the run flats in order. Plus, of course, the hard roof helps with noise insulation. Arguably less cool than the last fixed head version, but it'll still sell by the bucket-load.

Getting better all the time after the disastrous X3, but this latest BMW still can't match the materials Audi uses. Unlike the last version, the handling on this one is more fun, mainly thanks to a better steering system that's more precise. It's still not as clinical as a Boxster, but rear end grip is simply astonishing. It's a folding hard-top - how big can the boot be? You can at least get a Comfort Access option, so if the roof is folded it will lift up slightly so you can slide stuff underneath into the boot.
