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.

I had an excellent experience at Honda thanks to my service advisor, Robert. From the moment I arrived, he was friendly, professional, and incredibly knowledgeable. He took the time to explain what my car needed in a clear and honest way, without any pressure. Robert kept me updated throughout the entire maintenance process, and the service was completed quickly and efficiently. My car is running better than ever, and I truly appreciate the level of care he provided. If you?re looking for someone who genuinely puts the customer first, ask for Robert. He made the whole experience smooth and stress-free. Highly recommend!
Great Buy!

Bought a 2006 Mercery Milan here today.
Bought a 2006 Mercery Milan here today. No pressure from salesman, just straight up great person. Arthur did let me ask the questions and answered every one. He didn't try to tell me a bunch of B.S. Just to get me to buy a car from them. Absolute great experience and professionalism.

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.

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

Was in the market for a new practical vehicle as I lease a new Audi Electric. Wanted something I could jump in and drive, and moving to Texas it was only right I got my first truck. Young Kid Amir showed me two trucks and after two days and giving him a hard time we settled on a 2024 Silverado at a price we could both live with. If you are in the market for a vehicle hit up Amir at Classic Chevy he will take care of you
