I was in the process of converting. I rented a truck and flatbed trailer to transport my car. I bought this cover to cover my car in the trailer so people can't see which car it is. The lid came with its own straps, but I also had elastic cords that I used to secure the car. The total trip was 1593 miles and after two days of driving at an average speed of 60mph I have to say I was completely impressed that the cover survived the entire trip without tearing. Only problem was the straps that attached to the wheels came loose but after readjusting they held all the way to their destination. I am very impressed and would definitely recommend this case.
