Mine came from GPR. My wife and kids got it for father's day for me a couple of years ago
. They had it customized for my car. I'll post a pic later.
I ordered some parts from Dave yesterday and he said that he had a few more in stock. So far mine has worked well. It is an outdoor quality cover. When looking at covers I was really only considering indoor covers, but the wife thought it was a good idea to get an outdoor cover so I could take it with me to events and I could cover the car when it had to be parked outside -good idea! I haven't used it outdoors yet, but likely will at some time.
My cover is made by Covercraft. It is the Block-it Evolution material. I googled "Block-it Evolution" and was able to find good info on the cover.
I think that the price from GPR was about $140 but I am not sure.
