Conversation-piece looks, great engines, fine finish, solid feel, road-holding, well-engineered roadster hood, monstrous Z4 M
Looks aren't to everyone's liking, limited stowage space, hard ride in some versions
Intriguing-looking sports car that's a massive step up from the Z3, but keen drivers will still prefer the Porsche Boxster or Cayman.
For a sports car, the Z4's not terribly thirsty: the 3.0-litre Coupe, for example, returns 31.7mpg and even the Z4 M does 23.3mpg. The entry-level 2.0 roadster returns 37.7mpg.
Insurance costs will be relatively high and company car tax bandings hefty, but not ridiculous, M apart (with carbon dioxide emissions of 292g/km, it's going to attract a high BIK liability).
However, the largest cost in running a new car is depreciation and residual values should be strong, especially for M versions - with limited supply, these should make a good investment.
