Some of the reps in an old job had them, got to play in one a few times, we used to race them round the corporate carpark. Like go carts, feel a bit plastic but pretty good fun. Wouldn't fancy using it on the motorway though.
Been really impressed with cruse control (never had it before, never wanted it but great for those :tsktsk: average speed cameras on motorways).
Non-standard gotta be my Tom-Tom
