New and used 2025 Mercedes-Benz GLS 450 SUVs for sale near Elm Grove, WI

Bought my first German car, 430ix and it was a no brainer over the rivals at Mercedes-Benz and Audi. Got matched up with Tyler as the sales professional that worked with me, and his personality and knowledge was perfect for my personality. We built out a car with my specs and tried to order in March but with the shortages at the factory, we couldn’t fill my wish list. So we took to a Country wide search trying to keep as many things on my wish list as possible. Found one in Cincinnati and shipped it up. Love it! They honored my negotiated price and didn’t try to adjust it adding in shipping costs or discount my trade-in value. I’m impressed with the product and will buy a new one again someday and have no reservations to go back here.

Very friendly, helpful, answered my questions, helpful on the test drive in pointing out features of the car. Drove me to the bank to get the cashier's check. I would work with him again should the opportunity arise.

I've purchase four Mercedes and have ordered my fifth, excellent sales and service, I will be back again

Have not purchased a vehicle yet, but salesman Prentiss has been more than helpful with my car buying process.

Love , Love, Love the facilities . We also service our current vehicle at Elmbrook. We always feel welcome and treated as a valued customer. We will continue to service our vehicle.

Buying my Mercedes Benz here was the best experience. The people are very professional. They offer a variety of snacks and drinks. The salesperson showed me how to use all of the features of the car I purchased.

Excellent purchasing experience great repurchase and post purchase follow through by Jake Mooney. The entire staff, but especially Jake made me feel like I was purchasing a new car despite it being secondhand and not a Mercedes. Their new car lineup looked impressive and an overall great operation!

response was good but as like too many dealerships hte person answering the phone does not know much about the car and has to refer the question and that sometimes takes hours or days. Most of these people seem to be on the spot deal makers but are not really car people. Internet is ok but dealerships should have more consistent and knowledgeable people available. Hard for a customer to get information if it isnt already on the website..

Jake was phenomenal! It was his customer service and knowledge that won me over! I passed so many dealerships because Jake got the job done! In addition to Jake, everyone was welcoming and willing to answer all my questions! The entire dealership rocks!

Luke E. has worked with me now for the past two years and each time he goes above and beyond to make sure my car and my experience are excellent. He is bright, dedicated, and honest. 10/10.

There are two Mercedes Benz dealers in the Milwaukee area, and I’m glad I chose International Autos Group to service my vehicle. From the time I arrived to the time I left, I was treated very well by everyone. When I arrived, the service person was with a customer but immediately acknowledged me and let me know he would be with me shortly. Soon after, I had the Service Manager, Pete, help me out. Pete is professional, friendly and truly wants to help customers. He went the extra mile to ensure MB would cover any issues under warranty. I really appreciated that and the fact that they completed my regular maintenance quickly. Every staff member I interacted with was very responsive and friendly, from the sales people, admins and even the tech that drove my vehicle. Management: you make some quality hires so keep it up. If you’re looking to buy or need service, I highly recommend the team over at International Autos.

Idriz Idrizi was our sales rep and he was awesome. No pressure, super knowledgeable and great customer service. We shopped around a lot online and got a great deal on the exact car for which we were looking. The financial person we dealt with was fantastic as well. We felt we had top notch value, customer service and a great experience. I'll come back for sure to buy our next vehicle.

Had a great experience and got what I wanted for my trade in and the price of the vehicle I was purchasing. Never thought I would own a Mercedes, but here I am driving a new to me SUV.
