Pascuale and Sang were nothing short of AMAZING and professional! Pascuale met me at the door upon my first visit at the dealership. His kind and honest spirit allowed me to feel comfortable enough to know, this is the dealership I wanted to use. Pascuale and Sang properly prepared me prior to my arrival to retrieve my custom 2025 GLE350 to ensure zero hiccups. I did not feel pressured at all - just relaxed. My vehicle turned out EXACTLY as ordered! Sang walked me through the basics of how to operate my vehicle and I was also pleasantly surprised with a follow up call the next day from Sang.

I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

I had an excellent experience with Sayed at Sheehy Nissan
I had an excellent experience with Sayed at Sheehy Nissan of Manassas. He was professional, dedicated, and really focused on getting me the best lease deal on my new Nissan Altima SR. Sayed was efficient and made the trade-in process a breeze. Unlike other dealerships where it feels like you're asking for a favor, Sayed worked hard to make sure the deal worked in my favor. His persistence and commitment really set him apart. If you're looking for a new car and want someone who's going to work for you, definitely go see Sayed at Sheehy Nissan of Manassas
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

I recently purchased a BMW X7 from Auto Giants Mitsubishi, and I couldn’t be happier with the entire process. The staff was professional, knowledgeable, and really made me feel comfortable throughout the sale. They were transparent about everything — no hidden fees or pressure. The car was in excellent condition, exactly as advertised. Special thanks to the sales team especially to Jacob and Philip for their patience and excellent customer service. If you’re looking for a smooth and trustworthy car-buying experience, I highly recommend this dealership!

From the moment I walked into Fred’s Executive Auto in
From the moment I walked into Fred’s Executive Auto in Woodbridge, I could tell this was not your average car dealership. The staff greeted me warmly with an inviting environment. I was immediately impressed by the professionalism and the no-pressure atmosphere, which made the entire experience enjoyable from the start. This family owned business went above and beyond to make sure I found the perfect vehicle that fit both my needs and my budget. They were incredibly knowledgeable about their inventory and took the time to answer all of my questions thoroughly. I never felt rushed or like I was being “sold to,” which is a rare and welcome change from many dealerships I’ve visited in the past. What really stood out to me was their honesty and transparency. The team provided a full vehicle history report without me even having to ask, and there were no hidden fees or surprise add-ons when it came time to discuss pricing. Everything was straightforward and fair, which made the buying process smooth and stress-free. The selection of vehicles at Fred’s Executive Auto was also impressive. They had a wide range of high-quality, well-maintained cars to choose from, many of which were priced very competitively. It’s clear that this team takes pride in offering only the best to their customers, and they don’t cut corners when it comes to vehicle quality or service. The financing process was quick and painless, thanks to their knowledgeable finance staff who walked me through every step. They helped me secure a great rate and made sure I understood all the terms before signing anything. I truly felt like they were looking out for my best interest throughout the entire process. Logan was incredibly easy to work and communicate with when dropping off vehicles for service or repairs. Efficiency and transparency with every step of the way! Overall, I couldn’t be happier with my experience at Fred’s Executive Auto. They’ve earned my trust and my future business, and I’ll definitely be recommending them to friends and family. If you’re in the market for a used vehicle and want a dealership that values honesty, customer service, and quality, look no further than Fred’s in Woodbridge. Five stars all the way!

Great experience, surprised with customer service
I am buying a used car after 8 years, and this was great experience. No haggle is what I care. I was not forced to buy GAP insurance or anything else. The only complaint is, the lady taking down payment at the cashier was hesitant to tell me the details of the transactions before making a payment and showing attitude, but everyone else was great. I highly recommend this carmax.

was recommended by family and friends to buy a car from this dealership, and now I understand why. Due to personal and financial hardships, I wasn’t able to purchase a car right away. Despite that, they generously provided me with a loaner vehicle at no charge, which was a huge relief during a very difficult time. Their kindness and understanding meant the world to me. On top of that, they even made a donation to the Buddy Walk organization. Their compassion and community support truly set them apart. I'm beyond grateful.
