You'd think the logical answer to the '3 series being not spacious enough' would be (a) buy a Touring or (b) buy a 5 series. BMW thought differently, and have plugged the not-quite-sure-it-exists gap with this, the new 3GT. Much like the slow selling 5GT, the 3GT is essentially a 5 door hatchback version of the 3 saloon. It's a 'lifestyle' choice, don't you know....
