Yeah, hot-foot it right down to the dealer, puff up your chest and demand your floor mats! Then, when they give them to you and apologize for their mistake, beat yer chest and tell them they SUCK and you are going to make it your personal lot in life to tell everyone how BAD they suck. This will be GREAT for your blood pressure and assure you will have one less dealer to work with...the one that sold you your Trac and the one that should more than most want to work with you in the future.
OR
Maybe you could go in, talk to a manager, let him or her know that you think a salesperson, who is human too and may have just started, gave you some incorrect information and you would appreciate your berber floor mats. Let them know that you love the vehicle and look forward to great service and a long, happy relationship and you would hate to see an oversight and misunderstanding like this start that relationship out on the wrong foot.
It's your choice...pick one!
