In Summer 2018 I purchased a 2006 Ford Taurus because the place was highly recommended by a family member. The car was a little more expensive than I was looking for, but I was willing to pay more because they assured me that they had inspected it THAT WEEK. Higher price in exchange for no issues seemed like a fair deal to me. On cars this old, they will not supply any kind of warranty. Again, because I had been promised that it had just been inspected, I accepted this.
Less than a month later, my car wouldn't start and was burning through oil and gas. Needs a new Mass Airflow Sensor. It was expensive to replace, and I wasn't happy about it. I called in and they told me that since I bought it without a warranty, it was my problem. I also noticed that the windshield wipers jumped and clearly had not been replaced anytime recently, and as soon as I drove off the lot, one of the back windows stopped opening.
A few weeks after that, my exhaust system completely fell off. The catalytic converter needed replaced. I had to get my car towed. I called and complained and they said that they sell these without warranties because they "don't know what the driver will do" and "don't have a crystal ball" (essentially blaming me for a mechanical failure that almost certainly formed prior to my owning the car).
Five days after replacing that, the check engine light came on, the car was shaking when idling, and it could barely accelerate. Turns out the last person who owned it replaced the ignition wire improperly and never removed the old one, causing the new one to be misplaced and melt. This certainly should have been seen during an inspection. I don't know anything about cars and once I looked into the engine myself I could tell that there wasn't supposed to be a cut wire just hanging out in there. Went to a new mechanic, got that fixed.
Six days after that repair, my check engine light is on again.
For anyone keeping track, that is: two major repairs, one minor repair, one worn out part, one mysteriously not working part, and an extra check engine light. I am not convinced they inspected the car at all, let alone as thoroughly as they claimed. And their salespeople (they don't have a customer service department as far as I can tell, because I just keep being transferred to sales) don't care. They got their sale, customer happiness and safety be darned.
