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 .

The mark of a great dealer for me is the service after
The mark of a great dealer for me is the service after the sale. I bought a Buick Lacrosse from the Blaine store, adding an extended warranty. After 15 months, I found another car at a different dealer that caught my eye and I purchased it. Having over 3 years left on the warranty, I contacted Mike at Bedrock and he walked me through the process to get a refund. Actually, he did almost all the work and after a few weeks I got almost $1900 back from the unused portion. I HIGHLY RECOMMEND THIS DEALER!!
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.

Had a good experience with Darrell and Bob.
Had a good experience with Darrell and Bob. No pressure. Bought what I was looking for. Thanks. Paul
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.

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!

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.

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!
