I bought one of the cheap ones from supercheap and it lasted for a while and then split right down the middle!! I then spent a little bit more on a heavier blue one (still from supercheap) and it is doing really well so far. I wouldn't say it is really waterproof but it keeps a lot of the water off. I can't remember the brand at the moment sorry. I'll check and get back to you.

Spend as much as you can afford because you only get what you pay for with car covers.

I am like you and the ute won't fit in the garage but it is small enough to fit on the verandah but it still gets a cover put over it.
