    Our seasoned buyers meticulously select vehicles of the highest quality. We scrutinize vehicle history reports, assess prior paintwork, and meticulously inspect all vehicles once they arrive to verify the condition. Handpicking only the finest vehicles, we set a standard that surpasses typical used car dealerships and we are confident we go above and beyond every dealer when it comes to putting out a quality product. Lifted Trucks performs an 82 point multi point vehicle inspection on everything we list on our website. We do our best to repair any major safety and mechanical problems, but we are human and repairs may get missed or passed on if we deem normal wear and tear for the year and miles on the vehicle. Keep in mind that pre-owned vehicles may exhibit normal wear and tear, such as rock chips, scratches, and minor interior wear. We disclose any significant wear beyond normal to the best of our ability and encourage our customers to request additional photos and/or videos from our staff for additional concerns.

    At Tradeline Motorcars, transparency is our priority.

The dealer is not responsible for specific accessories or options that came with the vehicle when sold new, some of these options might pull from the vin number and be listed on our website, but what you see in the photos is what the vehicle will come with, nothing additional. Images displayed may not be representative of the actual trim level of a vehicle. Colors shown are the most accurate representations available. However, due to the limitations of web and monitor color display, we cannot guarantee that the colors depicted will exactly match the color of the car.
