Maybe this will help.

Very helpful pic, ta muchly.
I knew about this problem before I picked my car up, but I was so excited and thrilled on the day that I didn't check a damn thing! I'd have spotted if it had only had three wheels, but that's about it. I've been meaning to check that point ever since.
Yesterday I just happened to park in the village with the front wheels turned sharply to the right. The sun was behind the car, and thanks to that picture is was easy for me to see both covers were in place, exactly as they should be. Which was quite a relief, as I wouldn't care to have been driving all winter without them.
Penguin, have you had any joy from that dozy dealer yet?
