Would do. Suggest keeping it on all the time as having the Mondeo on your drive has devalued the house prices in your area by 50% overnight.

Should do easily. It goes over my estate. might not be quite as fitted at the back, but will work just as well.

Go for the extra large. Can understand why you are buying a cover if you own a C4 !

Probably not, only just fits a Berlingo

It will fit any estate car that I know.
Mine is an MG ZX estate; front bumper to back tow bar 4.6M or 15ft 1"
You may have difficulty in managing the under car ties which are a little bit too short for a wide car. The skirt is elasticated and should maintain a snug fit without the ties.

Difficult to say in view of the height issue but gut feeling would be yes. Seeing as this question was asked over two years ago, the car has probably been sold now !

Covers a Volvo V70 so should do yours

Yes it does. Make sure you get the correct size, but its not essential as long as it is big enough.

I used the XL on my ford escort. (usually on a Toyota estate) You end up with a bit of a flap at the back, but it still works just as well.

Read my review though before you buy.

not really the sides would'nt be long enough and the straps certainly won't

The extra large will be perfectly adequate. It fits my Jaguar X-Type Estate which is larger than a TT!
