Hi all. Can anybody recommend a decent car cover for outside use?

I use the Halfords one and it has been on and off cars for a few years now without issue. The Medium size is a great fit for the Coupe. I am sure there are better ones available but for under £50 I have been happy.

Brill! will have a look cheers

Yes. Autoexpress did a good review the other year, and Halfords were top.

Is it the "Halfords All Seasons Car Cover M 268806"?

I'm not sure Zak as I bought my Halfords cover a few years ago and sometimes they change the spec and product number. However I also have the All Seasons in medium and it's a decent fit and stays in place. Just be careful that you're not too rough tightening the under car strap buckles as I ripped the cover and had to tape it up.
When I use mine for this winter, I may place a softer indoor cover underneath to minimise rub against the paint work.

Another vote for the Halfords medium size here. It does what it says on the tin. Not sure how bad it is for the paintwork as I've used it on my silver coupe which doesn't have the best paint to start with.

If I was going to leave on long term I'd do what Gman suggests and use a soft one underneath.

I got the halfords all weather one this year and it leaked like a sieve so Sent it back. It looked like it was already a used item so I probably just need to get another.

Oh good point, I don't know how bad it is for letting water through, I use it mainly for stopping bird poop and the billions of bits of tree that seem to get everywhere if I leave it parked at my mum's house.

That's the one. I probably need to replace mine as I've had it a few years but it seems to be waterproof still, just looking a little dirty round the edges.

I did notice the other day that mine is slightly red from the door mirrors are on the car, but the lacquer came off them many years ago and they don't look to have suffered particularly in terms of the amount of paint now on them. I'll polish them before autumn when the cover goes back on though.
