Worst vehicle you've ever driven?

F30. And yes your right there was but every time i did it just flashed up unavailable on the screen although in all fairness, it could be a bedding in thing as my Kia stop start wouldn't work for the first 300 miles.
Regardless though, you would of thought a "premium" manufacturer could build a car with a eco feature that doesn't have to be turned off all the time otherwise you will fill the car with sick!
