We bought the car, as we have three other pre-leased ones, from a more than highly reputable dealership so we didn’t have any mechanic check it out. No need since this dealership would not dare sell one if they know it was a rollback. We know them very well. However, shortly after purchase, the catalytic converter needed to be replaced and a few other small things but at no charge to us.
I mentioned the rollback idea to our sales guy but he said he thought not.
