Used BMW X3 M for sale near Flemington, NJ

Mr. Tate was very professional and we liked him a lot. Good story and set-up to buy tire/rim package. Lots of pressure to buy that. Got us with one key upon leaving after transaction was done. Keys usually run around 500.00 and can be negotiated, so watch out for that. It was not disclosed to us that the car came with one key! That was a miss in our part and we should have known better. Because of having only one key it hinders me from using BMW ID as you need both keys for that. Overall, happy with the car.

Own a 2020 x3m competition . Bought it brand new. Not one problem to date 4/16/2025 Just like any vehicle....stay up on your maintenance and oil changes , tire pressure etc. all good love this car!

Bought my wife a Porsche Cayenne from the guys at CarsIndex on County Line Rd. She’s obsessed with it and as we all know—happy wife, happy life. Thanks again

I've had my X3M40i for 1 year and love it. Absolutely no problems at all. Just had my 1 year oil change and the oil was still clean. I highly recommend this vehicle !

Dealership was incredibly responsive to my inquiry - they were really great to work with. I ended up buying a car elsewhere, but J&S Autohaus was a pleasure to deal with.

Love my car! Got the Metallic Carbon Black with dark front grill and Oyster leather interior. Fits me like a glove. Easy to drive and handles very well. I do not care for the auto shut off at stop lights. They couldn’t get the chip to delete that so it is what it is. If I put it into sport drive mode, it doesn’t do it. Also couldn’t get passenger lumbar, due to no chip, and I do miss that. Great on gas too!

Cartopia is a great dealership excellent sales team. They were very responsive and were willing to work with me on my purchase. Eli was excellent and made sure everything was taken care of. I would highly recommend them to both local and out of state customers.

I love my 2020 x3m. I will own this until the wheels fall off and replace it with another x3m. The gas mileage at 19.5 miles a gallon is the only bummer but it’s well worth it.

I purchased a BMW from Cartopia. Adam worked with me. He went above and beyond to accommodate me during this process. There aren't enough kind words to describe the service level I received from him. I will definitely recommend anyone looking to purchase a vehicle to go to Cartopia .

Nothing like it. Definitely a sleeper. A rocket on steroids. This SUV is race car built for the track but made for the road. It corners wonderfully especially on hard tight corners. It has a sport suspension which makes it ride very harshly on runflats but softens up on Michelins. I didn't buy this suv for gas mileage rather I bought it for fun. Yet it averages 21mpg around 75-80mph. The seats fit like a glove.

In all our years buying cars from various dealerships, working with Chad Sanders & Ron Woods was the best experience my wife & I have ever had buying a vehicle. Everything was very straight forward, professional & honest.

The car performs well on the highway and has significant acceleration for Interstate driving. Ample room for vacation trips to take luggage and golf clubs.

Jonathan was great thank you for helping me purchase my Cadillac jeep wrangler you were great

I’ve owned a 2020 x3m competition since the month they were released. First let me knock out rough ride thing. If you ride on the stock Conti summer tires all the time, yes it can be rough. I switched to to Michelin all weather after 11,000 miles and it made a huge difference! A much better more comfortable ride Side note: when I would swap Conti to winter tires also a huge difference! The stock summer tires that come on the car are incredible for handling on a track which the car was made for but, the car feels much better with Michelin all sports all seasons. This car makes me happy every time I drive it ! So much fun to drive!

Thank you CarTopia for an amazing experience, I had all of my questions answered and they were completely transparent. thank you to Sabrine Eli and Mauricio for working with me and reassuring me that I left feeling like I got an excellent deal on my 2021 X3 M! no hidden charges and a very smooth process. I recommend all to come check out CarTopia

What can I say. Overall a great experience. They really enjoy what they do over here and the stock of cars is amazing!! One word of advice is make sure you check every small detail. The sales people can miss details and so can you. They move cars QUICK here and the sales reps on a Saturday seemed very busy!! The dealer had burgers and drinks to share with us while we waited which was awesome. Before I met the owner and his son, I was getting the feeling this was a family business, and it is! Really a great experience and awesome selection of cars. A++ dealer for used high end cars!

Best Experience I have had purchasing an automobile. Salesmen was a young professional who knew the product inside and out and was quick to alert and educate me on all of the nuances of the car, an AMG SL-55. Price was far and the entire transaction was stressless. I highly recommend J& S and my salesmen Max.

Absolutely love this SUV. Had a M340i and it was quick, but this X3 M Competition is wicked. Love the quickness and the firm ride. Glad I made the switch. Lots of talk about the firmness and the rigid handling, but try one and see for yourself.
