I am a returning customer. I trust this dealerships sales and service. I have know many of the staff for years and have always been treated like part of the Legacy family. They keep a great selection of vehicles to choose from and the pricing is always fair.

I have always hated car shopping but Allyssa made this the best experience I’ve ever had. It was stress free from the very beginning of the process and the finance portion took all but 5 minutes so I was very impressed with the entire process. I will be a Legacy customer for life and I have already recommended Allyssa to a few people and I will continue to do so. She is a very important asset to your company! Her product knowledge and professional is top notch which you don’t find that often in the sales industry anymore.

Great group of salesman to deal with. Gino made the buying process as easy as possible. If you are in the market go check out Legacy GMC.

The best dealership anywhere. We were treated like family no pressure no hurry. The salesman Zack was a true gentleman with passion for his job and pleasing his customer. Couldn’t do enough to make sure we were comfortable and chose the right vehicle for us. The product specialist Jacie was also patient kind and very helpful. You can tell the ownership of this dealership has hand picked great staff to promote his vision for great customer service. the management to the sales staff we all just great. They took the stress out of buying a vehicle. I recommend this dealership with a 10 plus only because 10 is the top. I would recommend it highly just call me il tell you in person.

I bought two cars from Legacy and I gotta say, I really enjoyed doing business there. I wanna thank Tyler, the Product Specialist, and John, the Salesman, for being so professional with my family and me, and for helping us get the deal done. The Legacy team was awesome and I'd totally recommend buying a car from them. I was also super impressed with how much inventory they had and how good the prices were – everything was priced to sell!

Most dishonest people I have met in my life, I tried buying a GMC Sierra Denali, and just because I already had my pre-Approval letter from my bank with a 4.5%, they did everything possible to not sell me the vehicle, unless I financed thru one of their banks with a crazy interest rate, the only thing they were honest about was that they told me if I finance with them at a high rate I could refinance with my bank after 3 payments, everything else that came out of their mouth was lies.
