Hi there. I will go ahead and add some actual facts here seeing as I have worked for Enterprise Rental for 10 years and have some intimate knowledge of the subject
We turn over approximately 350K vehicles a year. We are, in fact, the largest car dealership in the country. Now, if you want to avoid dealerships, by all means, don't come to any of our dealers. With that said, if you are going to use a dealer, buy directly from us. We keep the best vehicles, often coming from our fleet division (so they have had only 1 driver), and sell them ourselves. They have had no major issues, and you can guarantee we get Maintence done more routinely and timely than most owners.
What do we do all the rest of the cars you might ask? Well, we auction them off where they are bought by dealers, who then sell them as used at the dealer.
I recommend heading down to our new dealer on Route 46 in Elmwood Park
