I had an excellent experience working with Rodney Brown.
I had an excellent experience working with Rodney Brown. From the very beginning he was knowledgeable, attentive, and genuinely interested in helping me find the right truck. He provided clear, honest recommendations, and I never felt pressured to make a purchase.
Very comfortable to drive and relax in!
This truck was exactly what I was looking for! Great ride, and it will haul every thing that I need it to.! Low mileage without new car up front expense!
