Casey, you do realize that you're talking to a group of pilots, don't you?
Price is THE most important feature of any car rental. Just look at some of the cars out in the Democrat lot, that guys actually drive around in, that should give you an idea as to priorities. Plus the fact that most rental cars, from reputable companies, are only a year or two old, and kept in excellent condition. As well, most of us are not car mechanics. That said, not bad for your first post.
