I searched cars on TrueCars and received guaranteed pricing with Sound Ford. We went in and the car we wanted, Thomas Nabu said was sold. We asked if there was another one and as he was finding out, which was no, we found the other car listed on the certificate. They did not give the guaranteed price and tried to say there was only a $1000 rebate when we had already gone to look at another dealer and they said the rebate was $2500. So basically, the dealer does not honor the pricing and bates you to come in. Do not trust TrueCars and the advertised price by the dealer. It is basically a trap.
We did purchase the car because by daughter wanted, but will I go back to this dealer again? NO!!
