I wouldn’t worry about what a sales person is saying about me while he’s having a beer with his buddies.
What do you do when a car delivered to you by a dealer is not the same car that you ordered? Don’t accept it, don’t sign anything, don’t pay anything, ask for an immediate refund of your deposit, and don’t go back to that dealership. That’s what I would do.
Before you walk out of a dealership after ordering a new car, you should have a written copy of the car order. The order should specify the year, make, model, drive train, exterior color, interior color, option packages, and accessories. You can write in stipulations on the sales contract provided the sales manager approves and signs it. I’m not a car buying expert and this is what I did: I wrote in an “anti-bush” sentence. To “bush” comes from the phrase “to beat around the bush” meaning to delay or stall the completion of something. I wrote it in for my last new car order, a Nissan. It went like this: “If the car model year, model, color, options, and accessories as listed above at the price agreed upon listed above, is not delivered to me by such-and-such date, this sales order will be null and void and the deposit immediately refunded to me.” The sales manager approved it. The dealer said it would take 4 months to get the car. I gave them 5 months. It arrived in 4 months. Everything went smoothly. This anti-bush sentence gives you an out just in case the wrong model is delivered to you or if it takes too long to arrive. It worked for me.
