Thanks for the advice - my wife has had the car for about a year and one of the bodyshops suspected they had been done just before she bought it.

First time I cleaned it I certainly took a lot of mud out from under the lip. She absolutely loves the car otherwise - as do I when I manage to prise the keys out of her hand! so looks like we'll have to bite the bullet and get it done properly as I don't think she'll part with it just yet. On another subject, when we have been using the aircon recently and the car has been sitting for a while after stopping the screen mists up - I have heard that this may be a problem with the aircon filter??
