Fairfield's Buick GMC

I gave a price I was willing to pay for a vehicle and it was accepted. I drove 2 hours to get to the dealership and took the car for a test drive. I sat down with the salesman to make the deal and he went in to ok the deal with his GSM. The GSM who ok'd the deal sent the salesman out to tell me he wasn't honoring the deal. At this point I handed the salesman my phone with the accepted offer being ok'd by the same GSM. The GSM still said no. Poor practice by an established dealership. Wasted my time and gas.
