I once rented a car from 'Hertz' in TX while visiting. After I got the car off the rental lot, I stopped and checked the engine oil (and lights/horn/fluids under hood that were safe to check). I found the engine oil black as tar and it sure wasn't very free-flowing. I vowed right there and then to NEVER buy a car that was listed as once being a rental. SCARY, it was. very scary.
