I will never ever ever ever ever ever use a roof rack - that's the kind of thing that would happen to me! Plus I'm only a smurf (5ft 4) and would need to take a stepladder everywhere to get the bloody bike on and off.

I (and the OH) drive big cars - I have a diesel Mondeo hatchback which is actually huge and has the turning circle of a barge and is the most common and uninspiring car in the world but fits both our bikes in with wheels on, even fits in the tandem, with wheels out. The OH has an Audi A6 which fits everything in...but goes through petrol for fun (I swear I've checked where its been parked in case there is an obvious fuel leak).
