I recently purchased a used Nissan Armada from Petro. I took it for a test drive and fell in love with it. I was told it had been through an inspection so I had nothing to worry about. I drove it from Hattiesburg to Baton Rouge that evening. It wasn't until I got back, that I was told I had no back lights working. I drove in the dark for almost 3 hours with no lights.
The next day I had someone ride with me and they noticed the switch on the passenger seat was broken.
I called Petro and told them about the issues. They said they would fix the lights, but that was it. They said they had taken so much money off the vehicle that they wouldn't do anything else.
My advice is, if you buy a used car from Petro, make sure you inspect EVERYTHING yourself before buying it.
