We drove one when buying a new car for the other half earlier in the year. Even she hated it to drive, which says an awful lot about it tbh.
Access to the back seats was rubbish for a 5 door car, it drove like a sack of spuds with absolutely zero feel from the pedals or steering and I personally found it a bit awkward to see out of.
The one aspect I found acceptable that tends to get picked up on elsewhere was the boot. With the floor set at its lowest it was pretty similar to the fiesta, which in reality is a similar sort of size inside as the rest of the Joke (this was a facelifted car ) so pretty much matched my expectation
