Used BMW M340 for sale near Haslet, TX

Exceptional service. Recently, I purchased 2 vehicles from ECarOne in Plano TX.  My experience with ECarOn from my Sale advisor Dau Nguyen to Ash Osman in Finance was smooth and painless.   I communicated with Dau a few times regarding the Price of these cars and Trade in values, approx a week before we drove from Houston area to Plano.   Dau was very courteous, professional, straightforward and gave me a fair deal on the trade in.  I felt comfortable enough to drive 3.5 hrs to see him.  Once we arrived at the dealer, cars were in front ready for us to test drive.  With Dau's help, we were in and out with the new cars in a very short time.   We got two beautiful and in almost brand new condition cars, a 2021 Maserati GranLusso Levante for myself and a 2024 BMW X1 for my daughter.  Ash was easy to deal with, he did not hassle me into something I dont want and gave me a good deal on the extended warranty which I asked for.   I found my car dealer in TX now, and I will be back in the future.  I strongly recommend Dau Nguyen and ECarOne if you are looking for used luxury cars in great condition at good prices.

Thank you very much. They were supportive and respectful. My salesperson, a wonderful young man named Eduardo, helped me through the process of buying my first car very well.

I almost bought a BMW 325i, 40 years ago. My new BMW M340ix is perfect on looks, feel, handling, drivability, power and size. I guess what they say is so true; Better late than never. power and size! Almost bought a 325i 40 years ago but still better late than never. It’s really not just a catch phrase for sales, it really is; “The Ultimate Driving Machine”.

Carl Miller answered questions I forgot to ask. Straightforward and not pushy, very refreshing. I would buy from them again. This was an out-of-town purchase and it was a piece of cake to get the job done.

As fast as my 911 but I can drive it in the winter without special tires. Great suspension, brakes and gas mileage. HK stereo is terrific. Wonderful value. I only wish the sport seats were a bit wider.

I bought my Countryman from the dealership and had a great experience. It takes a while in the service center, but they are usually very busy so it is to be expected.

Value/performance for the price is phenomenal. It is probably more of a younger persons car as it rides low to the ground and has a hoppy feel to it.

I have always had a very good experience with the Moritz service department until this last time when I was back in less then 30 days.

Unreal performance and the absolute best of both worlds... in sport plus it is a BEAST. Period. Like less than 4s 0-60, regardless of official specs. In eco I'm getting 40mpg!! Show me another car that does that and looks this good doing it.

Just finished another service visit on my M8 and as always, Nathan Meyers was great. Friendly, always on time, very knowledgeable and went out of his way to explain what was needed. There is simply no better place if you own a BMW. I will always come here for service. Thanks Nathan

This is not my first rodeo with eCarOne and it's always been an excellent experience. I even got a better discount this time. I definitively continue to buy my cars from them.

Very professional, quick and smooth transaction. The best experience I have had with a car dealership.

My issue could not have been handled better! Perfect in every way. Thank you all.

Is amazing even on eco mode, but on sport the car turn into a beast. The interior desing in very comfortable and the features are super useful.

Salesman super professional and respectful and patient, no bad comments against him , happy with my purchase

Great handling vehicle, awesome safety features, love the technology. Overall a value for the cost, BMW got it right. Drove the competition and this was the best option for me.

I have purchased four vehicles from ECarOne and every time they have continued to impress me. Worked with Vinh in sales and he was very knowledgeable and never pressured me. Financing through the dealership was better than rates I got through my own bank. I would highly recommend ECarOne to anyone looking for a high quality vehicle at a great price.

they replied to all of my messages and were easy to work with on numbers

I had an exceptional experience with Gavin S. and the team at Sewell BMW of Plano. They went above and beyond to ensure I ended up with the perfect car, showing incredible patience and flexibility throughout the process. Their dedication to customer satisfaction was truly outstanding. Highly recommend!

Great experience from start to finish! The only thing that could have been was the weather....and they said they tried!

Mike Scholz was very helpful as I was looking for a used Mazda Miata RF.

After seeing the car online, the discussions with Kim at Sewell were professional and to the point. Car properly described online. Transaction was very simple. Car is very nice and I am very happy.

Best car buying experience ever. Worked directly with the salesperson for all the business activity. No closing booth/table. No pressure. We had one follow-up issue which was quickly addressed.
