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.

This has been the best experience at purchasing a vehicle, my salesman was Lonnie and he was absolutely amazing and walked me through everything. I will definitely comeback again. Great job
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.

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!

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 stepped into National Motors of Ellicott City, I was met with a friendly, professional environment. Buying a car can be overwhelming, but Johnson made the process easy and not stressfull . The dealership had a wide selection, and everything was clean and organized, which set a great tone right away. I ended up buying my car at a great price. 2.

Excellent Experience
I wanted to purchase a new vehicle. The vehicle I seen online I thought was a great car, Mr. Joel Lisman found me a even better car with less miles and cheaper then the car I was looking at. Once I came to pick up the vehicle I was at Carmax for less than an hour, then I was driving away in my new car. 😁

Mr. Wright (salesman) and Ms. Hana (financing), provided awesome customer service. They were NOT pushy or unhelpful. Ms. Hana looked at the apr my bank was charging me, and provided me a MUCH lower apr. They made me feel like a valued customer.

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.

The proficiency, expertise and professionalism of Euro
The proficiency, expertise and professionalism of Euro Motorcars Bethesda is second to none. My review would be meaningless if I didn’t give very special acclaim to the key associate who contributed great to my extraordinary experience. BRADY INFIELD is one of your greatest assets. He exhibits the professionalism, courtesy, patience, energy, enthusiasm , character, empathy, intellectual curiosity, self control, and self esteem that any organization would need to to advance their agenda! After all, you sell classy cars so you should have class, such as Brady Infield, to embellish your mission. It’s small wonder Brady Infield is a rising star with an enormously bright future; he’s under the tutelage and support of Tyler Griffin. Thank you Tyler Griffin and Brady Infield!

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.
