I agree, but that's hard to do when you're buying a used vehicle with no history. I don't know if the previous owner(s) used premium fuel, mobil1, religiously changed oil, spark plugs, etc. I don't think keeping it out of the sun is going to do anything but protect it's beauty. And then I can go out and get a Subaru with 100k on it and not have to deal with any of those issues, so there's that.
