This transaction was primarily done online because I live
This transaction was primarily done online because I live 6 hours and 40 minutes away. I completed an online contact form but ended up calling the dealership. Julian was my sales person and he was great. He answered all of my questions promptly and returned calls promptly. Everything was lined up for my trade before I drove up, which saved a lot of time once I got there. This was not my first distance purchase. Their warranty on used vehicles is part of the reason I chose this particular car and was willing to travel over 6 hours to get it. I highly recommend Julian for anyone considering a vehicle here or who is purchasing long distance. Everyone I worked with was great and when I needed a temp tag after the sale due to Kentucky law, it was handled promptly. Even after the sale was complete, they were still available and handled the issue immediately. Five stars.
Sharp looking vehicle
Sharp looking vehicle on the inside and out. Looking forward to the first snow fall to see how the vehicle performs on the snow covered roads.

We purchased a 2020 Lincoln Navigator from Mike Cook at
We purchased a 2020 Lincoln Navigator from Mike Cook at Westpoint Lincoln on 9/10/25. We are 72 years old have never had a better experience buying a car. We were very specific in what we wanted and they got one in. We live in Indiana and flew to Houston to buy it. Mike even picked us up at the airport and made the whole thing very easy. They had it in tip top shape and a better price than other dealers. We were very pleased with everything and would buy from them again in a heartbeat. Especially want to thank Mike for his attention to detail and his thoughtful courtesy. We consider him a friend. We feel very blessed. Highly recommend this dealership and Mike Cook

Highly recommend!
Highly recommend!! My husband and I stopped in just to look at some cars. We weren't sure what we wanted but was very surprised at the patience and time Ryan took to help us find the perfect car for our family! Our credit had taken some hits lately but he still found us a great single digit rate. Do yourself a favor. When looking for a car stop by and see Ryan.

Rob is your go-to Ford guy!
Rob has helped us with two cars this year. He listens to the customer and their needs. When you visit this dealership, ask for Rob! Nick, from the finance department, helped us this time. He was awesome too! However, I can?t say to ask for Nick because both of their finance people at this location are amazing. Prepared, quick working, and doesn?t dwell on paperwork or trying to sell more. Long story short, you?re in good hands.

We had a wonderful experience at Unique Auto Group. We found the vehicle online and called to say we were interested. They had the vehicle pulled out and ready. The price was excellent and as advertised. No hidden fees or problems. Amir was great! He helped through the sales process, and everything went without issues. I highly recommend buying a vehicle from Unique Auto Group! We will definitely buy from them again!
