Great Experience!
Ernest helped us with purchasing our 2022 Tahoe. Ernest is patient with our questions and did everything to help us feel confident in our choice. I would recommend Fitzgerald to anyone! This was a great experience and I look forward to coming back for our next vehicle! Thank you Ernest and Team!

Jeep Compass 2018 - 33,000 Maintenance
The person who was assigned to me did a great job. I left my wallet at home and she went extra mile to arrange for a shuttle to take me home and back to finalize the work. Great job!

We had an excellent experience with Kevin and Pedro buying a very nice, very competitive priced and well maintained, Ford F-150. They got us a very low/fair good rate on credit, and they also were very friendly, professional, honest and quick with the process. There were no surprises or issues or switches. Very reputable and trustworthy dealership and I’m really glad I bought the truck! It’s running great

I read the reviews, considered all the good and the bad
I read the reviews, considered all the good and the bad and still took a chance. Found a local person familiar with the type of car for a PPI. They di fix the AC on their dime. The car did have a minor accident on the drivers passenger door, not reported on the Experian report. This was not a deal breaker for me. I chose to fly out of state to make sure I got the title in my hand. Everyone was pleasant to work with from the moment I contacted them. I took one star off only because I arrived around 10:30am and wasn't able to leave till 4pm. I drove the car 500+ miles home without any problems.

We had a great experience at DARCARS Volvo in Fairfax.
We had a great experience at DARCARS Volvo in Fairfax. I reached out to confirm the availability of one of the used cars and Tim, the manager, quickly responded. We made an appointment for the next day and the car was out front ready for us. Tim referred us to Lonnell, who was very personable and straight forward. We were happy with the car and settled with their finance manager. Not huge space, but very comfortable and nice layout inside.
