Customer Testimonials


The service shop at Mills was amazing. James Dent was accurately able to dignose the leak from my Acadia and fix it promptly. It’s been a few weeks now and there absolutely no leaking. The service was fast and very reliable. The lady at reception had an uber to pick me up as soon as my car was ready. The service advisor Kyle, was very friendly and has great communication skills. Highly recommend this service shop for all your needs.

Great place to work

Great service, getting car keys cut. Very accurate !

I have a complaint. I just read through about 30 reviews and I’m stunned Kyle Robinson hasn’t been mentioned yet. I brought in my suv for servicing, first time dealing with this business myself (my husband dropped and picked up my car once before). From the very beginning, dropping off my car before doors opened to the very end, communication was excellent. I was explained where and how to leave my vehicle. Kyle throughout the whole process communicated with me often to bring me up to speed. When issues arose and my car had to be kept overnight, he ...




Angie is awesome!

The best of the best

Top notch dealership. Very informative, highly recommended. Ask for Al Clark if assistance is needed.



I've been wanting to buy a truck for quite a while now, and with the chip shortage, trucks were hard to come by. I spoke with Nick over a year ago and told him exactly what I was looking for. When he finally got the truck I was looking for in stock, it was only a matter of days before delivery! Highly recommend Mills Motors - best vehicle purchasing experience I have had - and I've had a few!

Good service

Dave at service is awesome! I dropped off my car for a regular service this AM. I was greeted by Dave, who is very delightful and one can really start your day on bright side. On my return trip to pickup the vehicle, I met Dave again and strike another conversation that made me felt I was a value customer. Thanks Dave. Gilbert

I met Al Clark 4 years ago and he was so helpful in getting my first GMC truck. Al made the process very easy and man! What a truck. When I was in the market for an upgrade Al was able to get me another great truck and a price that was better than expected. The truck is great. But Al... he’s the reason I returned to Cliff Mills. Thanks Al!

Al Clark and Dave from the parts dept went above and beyond in the customer service department. When I told an old friend Al that I had a 2008 Saturn Astra that I needed clutch parts for, he just smile and gave a little laugh and said “have I got the guy for you”. He connected me with Dave from parts. Dave found the correct parts that I needed in a timely manner and even stayed after his shift was done to accommodate my drive from the airport to allow for the pick up. Thanks guys, and the car is running ...

Our family has bought and sold cars from Mr Clark at Mills Motors for years. He is always friendly and willing to help in anyway he can. He works hard to get you the best deals, he’s our go to guy.

Al Clark has been extremely kind, and very knowledgeable in every purchase myself and my family have made over the years. There is very few salesman who will give and share their attentiveness and vast expertise like Al Clark. Should you be looking for a vehicle, do not hesitate when you walk in to Mills Moters to immediately have Al Clark paged. Trust me.....hands down he is the best in the business.

I enjoyed shopping for a vehicle today. The sales associate was not pushy, he listened to what I wanted so he could pick the vehicles that would suit me. I ended up taking one for a test drive and Bingo I got exactly what I was looking for. All the personnel were very friendly and kind. I went to another Car dealership before Mills and basically walked in and out. Way too pushy for my liking. So in my books listening to the customers needs goes a long way. Thx.⁹
