I went in to see a Sierra SLT advertised at a great price. Test drove and started to negotiate and after first round numbers weren't where they were working. Working to get to numbers that work the sales manager came over and said the price online was wrong and the truck is actually substantially more in price. Mind you this is after they already presented the car priced as it was online in our first round of negotiations. Shady practices here and I would encourage people not to take the time to even entertain any advertised prices as they could be different at any point. I plan on reporting this to the BBB.
