Stress free, best dealership we have bought from.
We have FINALLY found OUR dealership! The entire process was a welcomed change, Thank You! We never felt pressured, stressed or had others expectations weighing in on our decision. Chevis was our salesman, he worked for us to get what we wanted at the price we needed, without his effort our new AT4 wouldn't have been a reality. Alicia in the business office was as down to earth and chill as you could ask for. She didn't pressure us at all, let alone hound and demand like my other experiences with final documentation process of vehicle buying. The GM, made time to get to know us and made sure our deal was enjoyable. All in all, in the future, we will drive hours to this dealership for the service, product knowledge, and professionalism.
This truck has a jerk when changing gears sometimes.

Working with Scott and his team at Victory Hyundai was an overall great experience in the purchase of our new Tuscan SUV. We felt comfortable and greeted with a smile as we came through the door. We really appreciated that Scott was extremely personable, knowledgeable, friendly, and honest without a high-pressure sales approach. Along with great incentives and an over the top warranty package, we couldn’t ask for a better deal from any other car dealership. We look forward to using their maintenance service and highly recommend working with the Victory team.

Well organized operation - quality cars - excellent sales person - hassle free process - Don't offer great deals however. If you go to a another dealer, you can do better but you will have to work hard to get the better deal and probably put up with irritating car dealer tricks.

Taylor Swagger Is The xxxx 100%
I have personally bought two different vehicles from this dealership they were both used and they were both very reliable cars. I have to make a shout out to my advisor, his name is Taylor swagger, I have been asking him for almost impossible outcomes for the last 10 years, this man delivers everything I asked for plus. I just had a new set of tires put on my Camaro this week and an inspection and a muffler install two pass inspection. Taylor actually brought the tires that came off my car over to my house this weekend. Where do you find people like this? This gentleman has done everything under the sun for me and then use his own personal vehicle to bring me tires that came off of my Camaro to my house. I will never forget this gesture that this gentleman did for me, he didn't want to put my old tires in my Camaro so I can bring them home myself, again use his own personal vehicle to bring them to my house. What a guy
There are 20 matching cars close to your year range.
