NOT as Covercraft States in its Ad
Instructions ok BUT you MUST keep windows up to have OK protection. Design needs tweaking-rear side straps hook to body of car (Corvette--WTF)-Dumb design. I am working on a tweak so that they hook to wheels. Ok protection but on windy days the seal is not good on rear sides so dirt/dust will still blow in. Told Covercraft--Customer Service Sucks. WILL NOT Buy Covercraft Again. AutoAnything is Great. Covercraft Sucks.
For keeping interior clean between drives
I like to leave the top down on my Mustang when I'm not driving it and it's in the garage. I don't like putting the top up and down all the time so this is a handy way to keep the dirt and dust out of the interior when I'm not driving it. This is my second Covercraft cover and I bought this because the quality of the full car cover is very good. I like this one very much, and would only like to see a couple of minor improvements, One is the Velcro straps for the wiper arms need to be longer.
I had been looking for a cover to use for when I have the "boot" over my convertible top when it is down. This way I can leave the boot on, cover the car and feel like it is protected from sun, bird droppings and prying eyes. I would not expect it to protect the car from rain. The cover is serving the purpose I wanted it for.
