I can't really think of anything day to day that annoys me on our cars. I guess the only thing that's a bit inconvenient is that although in a saloon the rear seats fold down, they don't fold down very well or flat, and the centre seat belt gets in the way. And 1st gear is too short on a diesel.
Other than that, I think they did a good job convenience wise with our cars... until you have to do some mechanical work
