Just purchased my first MB from MB of Ff.
Just purchased my first MB from MB of Ff. Mitchell. I’ve bought MB’s from other MB dealers in the past. This was the best experience, due in part to the outstanding service from Sales Rep. Trent Nipper. Dealership is high touch in every respect.
Love at first drive
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.

Kendall was an amazing saleswoman.
Kendall was an amazing saleswoman. I love my car and the way I was treated
Awesome!!!
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!

Sedan vs SUV
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.

My daughter Kiyamma bought a Santa fe sport a few months
My daughter Kiyamma bought a Santa fe sport a few months ago and it has been great. I would like to thank you for her great experience.
A fun and enjoyable ride!
Yes, it’s crazy powerful but you can definitely tame it to be a fully enjoyable ride for everyday use. I look forward to many years with my new X3M!

We recently purchased a Porsche Macan from Napleton
We recently purchased a Porsche Macan from Napleton Maserati of Downers Grove, and I can’t say enough about the exceptional service we received from start to finish. Even though we’re located all the way in Seattle and never saw the vehicle in person before buying, the entire experience was seamless, trustworthy, and surprisingly personal. From the very beginning, Orsie on the sales side went above and beyond — answering every question promptly, providing detailed photos and information, and making us feel confident and excited about the purchase. His honesty and commitment to service were truly refreshing. On the financing side, Alex made the entire process smooth and straightforward. He explained everything clearly, helped us understand all options, and kept things moving quickly despite the distance. What impressed us most was the trust and transparency every step of the way. In an age where buying a car sight unseen can feel risky, they built an experience grounded in professionalism and care. We would highly recommend Napleton Maserati of Downers Grove to anyone — no matter where you're located. They proved that exceptional service and trust can travel any distance.

I had an exceptional experience buying my car from Duane,
I had an exceptional experience buying my car from Duane, he was an absolute pleasure to work with and went above & beyond to make sure I was taken care of. From the beginning he was transparent, honest, not pushy at all (which is always a good sign) and gave me the most fair price I found after months and months of searching for my exact car (Porsche Macan). There was a rare issue with one of my headlights, Duane made sure I had very nice (and fun) cars to drive while he had it taken care of - he even went as far to detail the car again and provided a ceramic coating which just shows the level of service you can expect from this dealership. I can't speak highly enough of Duane & his whole team - you can feel confident purchasing a luxury car here and know you are buying from the best!

Wonderful buying experience!
Great selection of cars, beautiful amenities and excellent customer service. The Jaguar we purchased was a better car in person then advertised. Jeremy was knowledgeable, polite and made the buying experience smooth, simple and easy. Give iAutoHaus a try when shopping for European Pre-Owened car and you will be happy you did.

I recently purchased a 2024 Lincoln Navigator from Heiser
I recently purchased a 2024 Lincoln Navigator from Heiser Group. I was pleasantly surprised at the amazing customer service they provided and the follow up to make sure I was happy and satisfied with my new vehicle. This is something I haven't experienced before so I felt like I was quite a special customer. They let me try out several vehicles to insure I had exactly what I wanted!! It's nice to see this customer service is still available as this experience was a far cry from my last vehicle purchase at a different dealership (no names mentioned). I left the dealership confident I made the right decision and I am confident I will be supported in any of my needs going forward. I will never purchase from anyone other than Heiser going forward. I recommend that everyone purchase their vehicle from Heiser!!
