I was a fleet manager for the old Premier Car Rental co before they were bought out by Budget. I sold plenty of rentals to individuals, some were low mileage that were in great shape others were dogs. Most cars we turned over at 20-25K but most of the subcompacts we kept for 50-60K. We bought most cars direct from GM and Ford but some were retired rentals from Hertz. Most people assumed they were maintained properly because they are rentals, most were but some were always neglected. I had a few Ford Espires (expires), Chevy Corsica/Berretta and Buick Skylarks that went 8K betwen LOF's and were never dealer maintained unless something broke. The only thing we were sticklers about were tires, brakes, alignments and inspections. Maint. wasn't my responsibility it was up to the individual office manager to maintain the cars properly and send me the paperwork. I just tracked cars from store to store, bought, sold, and made sure that the tags, titles, etc were kept up to date for a regional fleet of about 1K cars and trucks. My demo was always a Grand Am (a diff one every 3 months) and I took care of it.Loaners and rental cars sure are fine. Let this be a reminder why you should never buy one of those cars for personal use.
