Cherif is amazing he's still helping me find an
Cherif is amazing he's still helping me find an affordable vehicle. The vehicle I was to test drive was in an accident prior to my appointment. I'm a 63 yr old woman on a tight budget Cherif understands my needs and has been trying to find something for me, He is in touch with me daily, He has proven loyalty by his continued research of a car that is $4000 All my budget allows.For a salesman to work hard for me knowing I can only afford a $4000 car Is A Great Person .
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

From the Internet Sales Team, Mr.
From the Internet Sales Team, Mr. Danny, to the command central on the phones, Ms. Caroline, to the Manager in charge of client satisfaction, Mr. Kenny, and one of the best salesmen I have ever met, Mr. Brandon, this team will go above and beyond to help you find the vehicle of your dreams in your budget! Outstanding Customer Service - A Lost Art. And oh, by the way, if you have trouble seeing what is right in front of you, the door to the Sales Center is where the gib numbers 4000 are on the glass. There is no sign for that part of the facility, but it is the main front door facing West College Road. Hope they can help you out!
Nice for what it is
Meets my needs. Plenty of power. Lots of room. Hauls and tows like a dream. Very nice and stylish truck considering that it is a W/T.

Quick communication.
Quick communication. They were able to get me the information I asked for and worked with me to secure the vehicle I wanted. At the dealership, it was quick and the staff was very friendly.
Most dependable truck i ever owned.
This truck is a beast, but with the Duramax diesel engine, its fuel efficient as well. my best average is 21 mpg which is insane for a truck this size.

Dear Bickford Ford, My wife and I have purchased 8
Dear Bickford Ford, My wife and I have purchased 8 dealer sold cars over the past 45 years without a lot of love for the process or sales folks. Our latest car purchase of a 2025 Bronco Sport from Bickford Ford however was an exceptional experience all around. We had not planned to purchase a car but were in the neighborhood and simply stopped to see a Bronco Sport up close. We ran into Mike Mauer as he was heading out the sales office door. He asked if he could help us in a non-sales polite manner. We said we were interested in learning more about the Bronco Sport but were just looking. Mike was very accommodating with no sales hype or pressure. He is very genuine and knowledgeable. Based on our experience that day we went ahead over the following week settling on the trim package we wanted as Mike tracked down several options. Communication was excellent through e:mail, phone calls, and texts. We are from Chelan and had business in the area over two separate weekends. Mike found the specification we wanted in the Puget Sound area and even picked up the car himself when we returned the following Monday. The entire process was well prepared and faster than we had ever experienced – no “let me talk to my manager” back and forth. We traded in two vehicles as we were downsizing to one car. Mike under-promised and over-delivered in accommodating our selection and taking in our trades. Again, no sales hype. Just a great guy with integrity, sincere communication, and great follow-through skills. We were also impressed with the cleanliness and organization of the facility as well as the efficiency of the accounting and finance team. People seemed happy to be working there. Thank you, Mike Mauer and team for a great car buying experience! By the way: The Bronco Sport Sasquatch edition is an outstanding vehicle to drive.
Loved the Duramax Diesel and an incredible truck
Incredible truck. Wanted to trade it in for a 2020 same truck but unfortunately the interior for this year hasn't been updated. Supposed to next year. Will check in then. Would never consider a Ford or Dodge over this powerhouse.

I live in Waukesha I couldn't make a deal on an incoming
I live in Waukesha I couldn't make a deal on an incoming car, but I ended up ordering the car to spec from another dealer who had three allocations the dealers in Iowa, but it's gonna cost me $600 to ship the car which is not that bad because I'm saving thousands of dollars I previously purchased another brand of vehicle from this dealer as well but they're one of the largest Ford dealers in the Midwestern United States, which is how they ended up getting my business originally they have a big presence on all of the ford forums so the deals are out there people you just have to look for them. It's not 2022 anymore And ford sales numbers of public Especially when it comes to models like mustangs. But at least I tried to get my local deal of the business first and I provided evidence to them of the deal I could get because you know how it is. They always say that you're lying about the deal you can get. Etc etc etc Do your research you can always save money. It's a Ford. It's not a Porsche GT 3RS OK.

Mountaintop for life. Awesome experience
Found me a truck that I have been looking for. Had several on the lot but I’m very picky and knew what I wanted. Since they didn’t have the exact thing u was looking for, the salesman spent the rest of the day finding my truck. He went personally and picked it up and got it through service very fast and I was ready to roll with all tests ran and a great truck on top of it. Absolutely would go to this dealership again. Looking for a car and an SUV next year for the family. I will definitely be going back when I’m ready to pull the trigger on my/our next vehicles

Best Car Buying Experience Yet (4th Car)
If your looking for a diesel in Hampton Roads this is the place. Most dealerships have one maybe two. They have a WHOLE lot full of trucks and there is no way u come out of there without finding one that fits what ur looking for. Both in price and style/model. As soon as I got there I was greeted by Jason and he gave me the run down on all the trucks there in my price range. Looked at a few, took a test drive, and was out the door within an hour as happy as can be. BONUS: my wife discovered there was an issue with the sunroof. Jason made sure it would be fixed (in writing) prior to purchasing. I also got feel that if you go there for a vehicle and find anything wrong they would do the same thing. Great Experience and big thanks to Jason!

Not your typical used car lot
Me and my family have bought 4 cars from Jay Wolfe Auto Outlet. I have had nothing but top notch service from them the last 3 years that I have been dealing with them. Josh worked w me my first time in and got me financed when I was very doubtful that anyone could.

Amazing Service Frome Wendy Hosea
After getting over the honey-moon phase of buying my first “new” car I can safely say that everytime I enter the car I love it. From the Bluetooth technology to how the vehicle runs it’s just perfect. I have to definitely thank Wendy for her outstanding customer service, the patience that she had with me in getting the car ready, to helping me with the buying process she definitely went above and beyond and I definitely have to thank her for that! You guys have a real gem! We will definitely use her for future vehicle purchases!
