This winter my Williams 3 has had to be parked outside in front of my garage as the garage is full! We bought a cover for it that was relatively cheap (£40 i think?) It fits decently, not amazingly well but it does cover it all up. Am I better not covering it up at all and letting it bare the elements, or keeping it covered up? Im just concerned as I've heard leaving covers on that aren't tailor made can leave swirl marks/scratches on the paintwork. What do you think?
