747 miles for 21 year old truck
Jim Luttrell called me on a truck I was interested in when the sell fell through for previous buyers. Was already in Louisville looking at another. Took the chance to go look at it. Total 747 miles one way from my house. Easy process, glad he wore his mask. Bad thing....COLD weather!

Thank you Cable-Dahmer!
We went to just to look but drove away in a gorgeous new Chevy Trailblazer. Everyone went above and beyond to ensure we were getting what we wanted within the budget we needed. If you are looking to purchase a new or used vehicle, I would definitely go visit the team at Cable-Dahmer on Nolan Road in Independence. I am in love with my cute little new car.

Had a very good experience.
Had a very good experience. Julio, our salesperson, was very personable and didn’t pressure at all. If I had it to do again I probably wouldn’t have purchased the extended warranty. I did find a problem with the passenger side sun visor but we will see if they can help me out with it. I love the vehicle.
