I bought my Raptor from Tommie Vaughn Ford (shelter
I bought my Raptor from Tommie Vaughn Ford (shelter green) and it was honestly a really solid experience. Everything went smoother than I expected and there weren’t any surprises along the way. Jason in finance was great to work with. He explained everything clearly, didn’t rush me, and made sure I understood all the numbers. I never felt pressured, which I really appreciated. He also helped me get a really good deal on some warranties, so I left feeling confident about the whole thing. Overall, the team treated me well and made the process easy. I’d definitely recommend checking them out if you’re looking for a Ford. I’m loving my Raptor.
