Grapevine Ford Lincoln

Purchased a used car from Grapevine Ford and all went well until after the purchase price was agreed to. When the paperwork arrived I was surprised to see $1k+ in additional fees for LoJack and a replacement 2nd key. LoJack is what it is so I could only negotiate the cost down as it was already installed, a fact not divulged during the original negotiations. I questioned the lack of the 2nd key and was told they only received one when the car was traded in, so I agreed to pay for a new one to be made. After getting the car home I located an old service receipt including the original owner’s info. Upon contacting that person about potentially obtaining the missing 2nd key, they confirmed to whom both keys were given in great detail. Dealership maintains they received only one key. I ask you, does the former owner have anything to gain by lying about the key? At the very least dealer personnel lost the 2nd key and I’m left paying for their mistake. More likely this is a con job to sell highly profitable extras to increase the overall profit margin on used vehicle sales. I won’t be going back to Grapevine Ford-Mercury for anything in the future.
