I bout this truck new in 2008 and traded it in in 2020. This truck gave me 12 years of reliable transportation. I used this truck for everything from commuting to work to camping with the Boy Scouts.

They offer good Ford F150 4x4 trucks.
They offer good Ford F150 4x4 trucks. They offer full details on features. Unfortunately they only offer high mileage vehicles. 124k to 200K (too high). I am only interested in a Ford F150 2002-2003 4x4 with mileage not to exceed 60-80k max. I am a ready buyer with cash. ----- Robert LeBlanc
Great 4 wheel drive
I love the great 4x4 safety and comfort of driving. Not too many short beds out there and I love the blue color perfect for winter driving

I recently purchased a 2025 Chevrolet Trailblazer LS, and I have to say, the experience was incredibly smooth thanks to Becca, Bobby, and Brian. From start to finish, they made the entire process hassle-free and enjoyable. Their professionalism and attention to detail truly stood out, ensuring I had all the information I needed and that the transaction went off without a hitch. I couldn't be happier with my new vehicle and the outstanding service I received! Highly recommend this team for anyone looking to make a seamless purchase.
Incredible truck

Great service
They were pretty great, I worked with Matthew Smith. At first I got a Chevy Traverse, which broke down on me on the interstate. But they came and got it and replaced what was wrong, but I still decided I wanted to trade for another vehicle. It was a bit of a hassle at first but Matt really helped me out and reached my monthly payment limit for me. So I’m very appreciative of him!
Wish I still had it!
Sweet style and practical use for hard work. The miles per gallon were nice especially for Highway use. The four wheel drive was a blessing too.
