Great place to buy a vehicle, I found the deal on a vehicle I wanted online, sent a inquiry to make sure it was still available, Mark Talkington replied that it was, after a couple of emails verifying the deal I was looking for I went to the dealership, got there the vehicle was already pulled to the front waiting for me went on a test drive including the highway which allowed me to see how it handled while Mark went over some of the features of the vehicle, when we got back Mark asked if I thought the vehicle was right for me, we went in and started the paperwork, the whole process from pulling on the lot to driving away in my new vehicle was about 2 hours, Mark Talkington and Johnathan Cox made the whole process as smooth and easy as possible never any pressure to buy anything extra (yes they did offer extras and add ons, that is part of their job) overall a great buying experience and was well worth the drive to Jackson, when I need another vehicle Serra will be at the top of my list of places to look!
Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

I had an awesome experience buying my vehicle at QCautoplex/QCjeeps. The whole process took maybe 5 minutes, and they gave me the highest trade-in value by far compared to other places I checked. No pushy salespeople, no 4 square games, just super straightforward. I could not say anything bad about this place just a good experience quick easy see through experience.

Hidden Gem!!!!!
Saw truck on their website it was reasonably priced and looked very clean. Drove hour and half to get there was not dissapointed. Merlin was great to deal with upfront and honest. Facilities were very nice and clean. Buying process was simple and easy unlike big dealerships. Truck runs great will return when looking for another vehicle. Friendly courtious customer service! Many have complimented truck asking where we found such a great looking used truck. Burkholder Truck Sales is the place to go for used vehicles!

First time customer in Dallas, Tx
For some reason Mark's name is not on the list where it says, "Choose their name," but Mark was so helpful, patient, explained the process clearly and was very professional. I highly recommend him and would work with him and his team again. I would hope for a promotion for him Hyundai. :)

If you are looking for a new car, I would strongly
If you are looking for a new car, I would strongly recommend Willie Boyd at Corwin Toyoya in Boulder, Co. He was attentive, knowledgeable, and went above and beyond to ensure I got the perfect vehicle for my needs. He patiently answered all of my questions, explained the features, and even took the time to demonstrate how everything worked. It was the best car sale experience I have encountered in many decades of purchasing a new car.

Best selection of trucks period!
Best selection of trucks period! You can buy a new truck and build it like they do for a better price. Colby was extremely helpful and easy to deal with. He provided several options for my trade and financing. We needed up at the place that was fair and closed the deal! He even met me on his day off to pick up my new truck! Thank you!
