We bought our new Hyundai from Plaza Auto Mall a couple of years ago, and aside from it taking a long time to do the paperwork, everything was fine.
My husband took the car in for an oil change, and Vladamir told him that he needed the maintenance done too. Never told him how much it was going to be.
My husband almost had a stroke when he picked up the car and it cost over $350! He had no idea it would be that much and should have been told before the work was done. On the paperwork he had to sign it said that "customer acknowledges receiving original estimate of $400" which is absolutely not true. If my husband knew that it was going to cost that much, he would have told them not to do the maintentenance. The car didn't even need it yet and Vladimir knew that because he said it was a little early.
Because of this, they lost a customer for good. We're going somewhere else from now on. My friend is also a customer of theirs and they tried to pull the same thing with her and now she goes somewhere else for service.
Oh, and last time we took the car in, I stupidly left some money- about $15 for tolls from our recent trip-hidden in a book in the glove compartment and forgot to take it out. There was a recall on the airbags and I guess they had to take everything out of the glove compartment to get at the air bags. Lucky guy who opened and looked through everything in the plastic envelope holding the book where I hid my toll money. When we picked up the car, all the stuff that was in the glove compartment was on the passenger seat and the money was gone. I didn't say anything because I had no way to prove it was there. They should be ashamed.
