From the time we walked on the lot to look at their luxury SUVs..we felt welcomed and our sales experience exceeded any other dealership. We ended up buying a 2025 QX80 Luxe Model..absolutely gorgeous car They went as far as bringing us the vehicle when we started the financing process. I can't say enough about the customer service. If you ever decide to buy a luxury vehicle please go to Crest Infinti..you will blown away with the service they provide.

Fast, Friendly, and Helpful
I saw a 2014 Silverado LTZ that had all the features I had been looking for. I set my mind to drive up and look at the truck (I opted not to transfer as I had family in the area I intended to visit). The hold process is GREAT. It's a quick click and I knew the vehicle was going to be there after I drove the 3 hours to look at it. I worked with Chris Biggs and he was great. We talked options on the truck and for financing (they beat my credit union's offer). He was incredibly friendly to be around and my wife and I thoroughly enjoyed talking to him as we waited on our financing offers. He was thorough in making sure we had all the facts and options. If I had anyone in the area looking to buy, I would send them to Chris in a heartbeat. Then I know they'd have a good experience and be completely taken care of.

I recently purchased an Audi A6 from Epic Motors.
I recently purchased an Audi A6 from Epic Motors. The only complaint that I have is that I cannot give them more than 5 stars…they deserve it. Their professionalism, communication, timeliness and transparency were outstanding. From start to finish the process and interactions were not merely transactional but they were personable. Cristian, Mo, and Jose were excellent. Without hesitation I would recommend Epic Motors to others, and I would unreservedly purchase from them again.

No pressure No games Easy buy of a cash car.
I went to buy a cash car. I had a price range to follow. I looked at a Lexus 07 LS460. I was helped out in getting a deal for this car by Jesse. I had some some request to be addressed first, to make me feel better about the deal. I saw they where all made. Maybe not to a high standard but they were done. The whole process felt easy with no pressure. I never believed Jesse was playing games with me. Ever. All in all he sold me a car I wanted and at the price I wanted. What more can you ask for? It's a 07. It's got issues. Yes. It's a used car but the buying experience was never an issue. Would I go back to buy another one? Yes. Will I tell a friend? Yes. I just recommend you do your own research on the particular car your looking at. I did not and still got a good deal. Ask for Jesse.

I had the pleasure of connecting with Hopper MotorPlex
I had the pleasure of connecting with Hopper MotorPlex last week after a friend had told me about them. Wow, while I’m a car guy, purchasing a daily driver is not my idea of having fun. The experience rein-instilled by faith in purchasing an automobile at a local dealer. Gary, Randy and the entire team were professional and brought a transparent and a no nonsense approach to my selection and purchase. Check out their impressive, clean and varied inventory….. you will be glad you did! Until next time!

Cassidy and Charlie were the absolute best ever.
Cassidy and Charlie were the absolute best ever. The knowledgeable presentation of the Ascent far exceeded my expectations and what I thought I already knew about the vehicle. The rate the finance department got for me was better than what my own credit union offered. I highly recommend them to you and I already referred my cousin and his wife who bought a CPO ascent the very next week from them. You won’t be disappointed

Bought 2 Cars Here, Now Going Back
Bought a car here. After several years I traded it in and bought another. Values were fair on my trade-ins. Vehicles on the website are really the ones they have on the lot. No pressure, no negotiating, huge selection. Paperwork process like normal. I did have to refinance after I left there because the interest rates were steep and I got better deal from credit union. Overall recommend. Had a car accident, will return to Carmax.
