Every one was well informed and helpful.
Every one was well informed and helpful. My sales person was Matthew Boer. I felt very comfortable with him. Both due to his knowledge and attitude. A hugely different experience than I had elsewhere. He tried hard and succeeded in getting me the car I wanted. Joseph and Jonathan also deserve a mention. Thanks guys.

My mom and I went to at least 4 dealers before coming to
My mom and I went to at least 4 dealers before coming to Showroom Auto, I was in the market for a Lexus IS350 F-sport and we found a beautiful vehicle at Showroom Auto but it wasn't the car that made us purchase here, it was the interaction. Chris was really relaxed with us and he made my mom feel truly comfortable. He's a true professional and extremely knowledgeable in his field. I definitely reccommend Showroom Auto.
Mixed Feelings
I love the car and at the same time I can't help to hate it. What I love about the car would be the luxurious interior, comfortable and quiet cabin, smooth ride, ease of access, and a few extra features that were put in as an add-on. What I don't like about this car would be the poor fuel economy for the 30i model, especially when compared to the B-58 engine. Apple carplay connection issues, no option for remote start unless I want to void warranty, and no option for the iDrive Recorder App. Exterior Styling - 8.5/10 Interior Styling - 9/10 Comfort - 9.5/10 Cargo space - 8.5/10 Driving smoothness - 9.5/10 Horsepower - 7/10 Fuel Economy - 3/10 It's been an overall fun car to get around in. It's easy to get in and out of, smooth on bumpy roads, and it is quiet. The fact that only 2022 models and newer offer remote start and iDrive recorder is a big disappointment. But I think my biggest disappointment would be the fuel economy. As I had the B-58 in the past and averaged out 11.5L/100km and in this X3 am averaging 13.5/100km which was worse than my pick up truck. I might not keep this car for long-term just because of how poor the fuel economy is.

First vehicle purchase from the dealer.
Went in to buy a used vehicle they had in their inventory. The finance manager worked out a good deal with me to meet my needs in the vehicle i was interested in. The sales person Axel was great with comunication in the car i was interested on.
Excellent Car
I love that BMW makes a mid size suv that is part electric now. We purchased the x3 edrive. I do mostly local driving during the week so only need to fill up with gas once a month to every six weeks. Excellent car!

Best Purchase for the Value and Cost
The BMW X3 is not a crossover that should be ignored. It is more than I expected coming from someone who has owned a 3 Series BMW for the last 6 years. Now I ask myself, why didn't I opt for the X3 much sooner, especially since it is more spacious with better features than my 3 series. Plus the price was only about $3,000 more for plenty more space and amenities. You owe it to yourself to test drive one soon!

Best Ever
Probably one of the best car buying experiences ever. They showed me the car I was first looking at then 1-2 more options. I ended up going with one of the alt. options that actually had better equipment but at the same price.
My dream car
It is just what I expected. It drives smooth and I love it. I would recommend to anyone. The experience was wonderful and made my day. This is my dream car

After looking for months at MINI dealership in the
After looking for months at MINI dealership in the tri-state area and as far as Pennsylvania looking for used car I found that South shore Mitsubishi had the best sales team. The entire staff and all people involved were very pleasant and professional very helpful and very energetic about every aspect of the process unlike other places that seem to be just non-interested trying to just blanket sales somehow. The team from top to bottom or excellent and I would not hesitate to recommend the steelership to anyone looking for a good car and professional and courteous people to deal with.

If you’re looking for a group of honest guys and a clean car, look no further. Jerry and Jeff went out of there way to take care of me, and their cars are super clean and well kept. Would highly recommend Power Motor Group, they’re professional, honest, and nice guys. Would buy another car from them.

Great service with David
I had a great experience with my time at Masters. I was assisted by David and I must say he was a excellent salesman. He was very patient and understanding of my needs while shopping for a new vehicle. He’s prompt with his responses and is always available to answer any questions. Highly recommend him to anybody inquiring to buy a new car. Great thorough guy all the way around.

I recently had the pleasure of working with Claudia at Habberstad BMW, and I can confidently say that she is one of the best sales professionals I’ve ever encountered in the automotive industry. From the moment I walked into the dealership, Claudia made the entire experience seamless, stress-free, and genuinely enjoyable. She was extremely knowledgeable, answered every question with confidence and patience, and helped me navigate options that perfectly matched my needs and preferences. What truly sets Claudia apart is her genuine care for her customers. She wasn’t pushy or scripted instead, she listened carefully, offered thoughtful advice, and treated me with respect throughout the entire process. Her transparency, professionalism, and warm personality turned what could have been a typical car-buying experience into something memorable. Claudia went above and beyond to make sure everything was perfect before I drove off the lot If you’re thinking of purchasing or leasing a BMW, do yourself a favor and ask for Claudia. She is a true asset to Habberstad BMW and a shining example of what exceptional customer service should look like.
