I went to test drive a used GMC Son Honda had and the truck had a lot of miles so I didn t get approved from the bank. They ask if I wanted to check on other trucks and I said no thank you, I just want a gmc of this year model. I received in the mail my credit checks where they had ran my credit on multiple other trucks they had in their lot! That makes it a hard inquiry and negatively affects my credit score! I m not happy with my experience!
