eCarOne

“I usually don’t leave reviews, but the experience at eCarOne definitely changed how I viewed buying a car. After a bit of hunting around last April, I found a listing on eCarOne’s website for a 2022 Model S Palladium, fully loaded with lifetime FSD, as well as a very rare build spec. I decided to give them a shot, and was definitely not left disappointed. I can honestly say this was one of the easiest car-buying experiences I’ve had, especially making the switch from a Yukon Denali over to a Model S (very uncommon, no?). eCarOne guaranteed to match the trade-in offer of CarMax BEFORE they appraised my trade-in, and furthermore completely matched CarMax's offer (a very generous one, by the way) with no questions asked. The sales department, and my sales representative, Adam, were fantastic to work with from start to finish—professional, completely straightforward, and negotiable. As always, there may be some add-ons, but after some negotiations, eCarOne willingly lowered their non-haggle price just to ensure a smooth and easy sale! (Plus they gave a few extra add-ons included with the price!) Where eCarOne's experience really started to shine, though, was after purchasing. Most places usually leave you with whatever problems the car has. eCarOne did the exact opposite: I noticed the 3rd brake light had started to go out, amidst a couple of other minor issues. eCarOne fully covered the cost of my repairs AFTER I had purchased the vehicle, a bill of $2.4k if I had paid out of pocket. Furthermore, any inconveniences caused by this repair were also covered by their team. I am beyond astonished and impressed at this level of customer service. A few months later and the car is absolutely perfect! If you’re looking for a dealership that actually respects your time and their customers, I highly recommend and urge you to look at eCarOne, the sales department, and most importantly Adam and the manager, Michael, for standing behind their cars to the fullest extent. I would absolutely buy from them again, and highly recommend checking their cars out!”

“I had a surprisingly smooth experience at eCarOne. I was looking at a Mercedes EQS and saw a very attractive price for a car that was well within its factory warranty and in seemingly great condition. I emailed Paul as I was out-of-state and reserved the car for the next day. They said they were unable to hold cars for more than 24 hours which was disappointing but fortunately I was able to drive down to TX quickly. I received a very good quote for my trade-in online (they beat out Carmax by a significant margin), which they actually honored in-store so there were no bait-and-switch shenanigans. Paul sent me a video of the car before I drove down to show it was real, and when I arrived, everything matched up to what I was expecting and they had the car waiting for me for an unassisted test-drive - which I appreciated. The only reason I'm not giving 5 stars is because of the long wait to finalize the deal. I was the first person in when they opened at 9:00am and even though I was pre-approved for finance and my car was already appraised, I didn't leave until almost noon. It was perplexing to me as to why that process took so long, but other than that it was a very smooth process start to finish; the car is great, and there were NO dealer add-ons or slimy sales tactics. I was very impressed with the experience overall and would recommend to anyone looking for a lightly used car for a great price.”

“My husband and I purchased two Mercedes EQ vehicles on April 10th from Ken Rozenblum at eCarOne, so this review is for both of us. Overall, the sales process was smooth, and among the dealerships we visited, eCarOne stood out for its excellent selection of clean, low-mileage luxury EVs. There were a couple of issues with my EQE at delivery—the windows were not operating properly, and an A2 service warning in the dash indicated it was overdue by 190 days. Fortunately, Jesus Pachicano at Mercedes of McKinney resolved both issues the next business day. eCarOne covered the cost of the window repair and contributed $250 toward the $900 A2 service. While it would have been ideal for them to cover the full amount, the contribution was appreciated. Lisa Bassett, my Client Experience Specialist, was also very responsive and helpful in coordinating the reimbursement. I would not have felt comfortable driving the vehicle long-term with the service warning active. The only drawback during our experience occurred while we were finalizing our purchases. Another customer approached Ken at his desk, and he began assisting that individual simultaneously while still working with us. Both my husband and I were offended, particularly given the complexity of our transaction involving two vehicles. We're pretty sure the other gentleman only purchased one vehicle. In the future, it would be better to ask the other customer to wait briefly or have another salesperson assist, ensuring full attention is given to clients already in process. Despite this minor issue, I would still recommend eCarOne to anyone looking for a clean, low-mileage vehicle.”

“We had an excellent experience purchasing our BMW i4 from eCarOne, and I wanted to take a moment to recognize how smooth and enjoyable the entire process was. From start to finish, everything was handled professionally and efficiently. The team made the buying process straightforward, transparent, and stress-free, which is not something you can say about every dealership. A special thank you to Adam, who truly went above and beyond for us. He was incredibly kind, patient, and attentive throughout the entire process. He took the time to answer all of our questions, made sure we were comfortable every step of the way, and never made us feel pressured. You can tell he genuinely cares about helping his customers and doing things the right way. Even when we had questions or needed clarification on details, Adam handled everything with professionalism and a great attitude. That level of customer service really stood out and made a big difference for us. Overall, this was one of the best car buying experiences we’ve had. If you’re considering a vehicle from eCarOne, I highly recommend asking for Adam. You’ll be in great hands.”

“I can honestly say this was the smoothest car-buying experience I’ve ever had, and that’s saying a lot after owning 30+ vehicles over the years. From start to finish, Bryan Nguyen was outstanding — professional, knowledgeable, patient, and genuinely helpful without any pressure. He made the entire process easy and straightforward. The rest of the staff, including the finance department, was just as impressive. Everything was clear, efficient, and handled with professionalism. At eCarOne in Plano, there were no games, no unnecessary delays, and no surprises — just a well-run operation that truly respects your time. I was in and out faster than expected, and the communication throughout was excellent. If you’re looking for a dealership that actually delivers a hassle-free experience, I highly recommend eCarOne and working with Bryan Nguyen. I would absolutely buy from them again.”
