Easiest Pickup Purchase Yet!
Super knowledgeable staff. Easy to work with. Easy to talk to. No pressure what so ever. They work with your budget and get you the bottom dollar! Thanks again Country Truck and Auto!
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Craig was straight forward and honest we couldn't be happier :-) Went to others and felt different. He answered all our questions. Ask for Craig like the list!
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

very friendly
The sales staff was very friendly and helpful. They are not a high pressure sales team so I did not feel rushed in to a decision at any point during my visit there. They answered all of my questions and made sure that I was completely confident with them and the entire purchasing process.

This dealership was amazing and I highly recommend.
This dealership was amazing and I highly recommend. When purchasing my new truck, they worked with me to find a price that worked for the both of us. Then when I was an idiot and did not see hail damage due to frost, they further helped by paying for half of the hail damage repair. 5 stars is too low. Eric was awesome and all the managers were amazing. Can’t speak highly enough.
Beautiful truck
I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

I recently traded in my 2016 Jeep and leased a 2025
I recently traded in my 2016 Jeep and leased a 2025 Tacoma. The sales person I dealt with, Ron Smith truly went above and beyond ensuring I got a more than fair trade in value for my Jeep and found me a great new vehicle at a great price. I probably was not the easiest customer to satisfy but Ron stuck with me and was extremely patient and courteous. Ron maintained a great balance between being very helpful while NOT being a pushy salesman. If you are planning on looking for a new car I highly recommend Corwin Toyota and suggest you ask for and wait for if necessary Ron Smith. Thanks again Ron.

Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork

Worked with Cosmin on a used Porsche Cayenne.
Worked with Cosmin on a used Porsche Cayenne. Very friendly and professional salesman with a no-xx attitude. Didn't leave me waiting around excessively during price negotiation, and was willing to work with me to find a deal I was happy with. Finance was super quick and low-pressure, I didn't feel like I was being lambasted with upsells that I made clear I didn't want. Good stuff, Austin. Very respectful and professional staff, and I would definitely recommend doing business with these folks. Keep up the good work.
Very beautiful truck
This truck would help me thru out my needs I and my family love this beautiful truck, there is no better place for me to shop than the Paso Robles Chevrolet I highly recommend them

I dealt personally w Manny Rodriguez. He was intelligent, knowledgeable, honest and transparent. I applaud MM Chevy for hiring such an inspiring young man. Would go back again in a heartbeat!! I purchased a nice Silverado due to Mannys professionalism! Phil Bravo
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Awesome!
No pressure to sell. Byron was of tremendous help, knowledgeable, and loved to share his fathers great history in service to his country. He even sent me home with great reading material on him. Prestige went to long lengths to find the right car (my wife will ONLY drive a stick, drives me crazy!). No manuals on the lot, so they sought the countryside to get just the right one. I highly recommend prestige to anyone.

After any serving of a vehicle taking it through your car
After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.

Great Place to buy a car
I was in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.
Best truck I've owned yet
What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.
