I have to agree with you, Ayie. When my former van ( I had just paid it off ) was totaled when a tree fell on it two years ago in a winter storm, I found a used van at the dealer. It had 10,000 miles on it and had been a rental van for one of the major car rental agencies. It was a Dodge Grand Caravan with all sorts of bells and whistles and much more reasonably priced than I had anticipated.
