Looking for another car might give you a bit of a lift Mrrzy, a sort of project. But as Helen says, fixing the door may be fairly easily done, and would be cheaper than buying another car.
We have a dear little Ford Fiesta called 'Misty', which has 70,000 miles on the clock. But it's cheap to run, Tax and insure. The only problem is that the men at the carwash use high-pressure hoses, which has taken off large chunks of the paint on the front bumper. It won't rust (made of plastic) but Misty looks as if he has leprosy!
What's your dream car Mrrzy? Husband says he'd like 1) a Range Rover Evoque and 2) a Mini Countryman, both in taupe. I'd like that too. We merely need to win the Lottery!
