Overall, good responses -- thanks.

I have the item on my Amazon wish list and will consider getting one. Obviously, it would have been better to have had one long before now, our DD's are 6.5 and 9.5 years old, so that's a lot of winters. About a week ago, it got just warm enough that my wife went out and washed both cars twice, so the shiny sides look much better but cars normally don't start rusting there.
