What a pleasant experience.
What a pleasant experience. My first time financing a vehicle. When going to initially look at the vehicle, I discovered a few issues. Obviously no used car is going to be perfect, nor was I expecting it to be. They told me to come back the next day and the issues would be fixed. I came back and they did in fact fix the car. They are willing to and have went above and beyond.
best in class
My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

Sheehy always strives to provide the best service
Sheehy always strives to provide the best service possible. Their service team is top notch and they keep you advised on the status of your vehicle while being serviced. One of the best things I’ve experienced here is that they don’t try to sell you any services that your vehicle doesn’t need.
Better than my old truck
The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck

Best pricing in the DC market, we searched many vehicles and platinum auto sales has the best price for the car we were looking for by far so happy we came and bought here! free carfax was provided to us and great customer support
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

Five-Star Review for Autos Direct of Fredericksburg,
Five-Star Review for Autos Direct of Fredericksburg, VA I recently purchased a vehicle from Autos Direct of Fredericksburg, and I can confidently say it was one of the best car-buying experiences I've ever had. From start to finish, Gary and his team demonstrated professionalism, clarity, and an unmatched level of customer care. Gary took the time to walk me through every step of the process with ease and transparency. What stood out most was his genuine approach to customer service—he made me feel like more than just a sale. I left not only with the exact vehicle I came for, but also with deep appreciation for how seamless and respectful the experience was. Even after the sale, Gary went above and beyond to assist with a small but important request related to my trade-in. His follow-through and attention to detail truly reflect the dealership’s values. If you’re looking for a trustworthy team, great vehicles, and exceptional service, I highly recommend Autos Direct Fredericksburg. Ask for Gary—you won’t be disappointed.
