I’m looking and have been for a while.
I’m looking and have been for a while. I have found most car sells men don’t care what they say to sell a car. I was pleasantly impressed with a young man by the name of Luke Fox when showed me the cars and all that entails. When I make my final I hope I can buy it from Mr Fox. Thank you Luke
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

I recently purchased a 2020 Mercedes G550 from Top Line
I recently purchased a 2020 Mercedes G550 from Top Line Auto, and I couldn’t be happier! The car is absolutely phenomenal—every detail exceeds my expectations. The service I received was exceptional, going above and beyond to ensure a seamless experience. If you’re in the market for a vehicle, I highly recommend Top Line Auto. They truly deliver excellence in both cars and customer care!
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.
