I'm 6ft 5" and was surprised how much room there was in a Ford Ka which was very comfortable. It was only a Courtesy Car years ago but very impressed by it for local journeys.
It really didn't like London to Manchester and back in a day, probably because it was flat out both ways. My car at the time was a Mondeo ST200, 2.5 V6 which loved eating motorway miles
Would buy one if I needed something small for local runs
