Anyone have a link to any legit car cover tests? I am wondering how much heat protection car covers provide in general, and really more important comparison studies of some top brands and cover types. I found one place that posted results of their own covers, but who knows how legit that is. You know, even Myth Busters, or any somewhat scientific independent studies may be be at least something to look at. I have 2 SL MBZ I suppose I could put side by side in the driveway just to compare temps one with cover and one without for a basic test.
