Mercedes Service
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.
I’ve had many Mercedes-Benz models over the years,
I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

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!

Our trusted dealer/repair shop for over a decade!
We have been customers of Reina's service department for well over a decade where Lorenzo and his team have done wonderful work on our vehicles. Because of our trust in Lorenzo, when it came time to buy a car 10 years ago, it was on his advice that we chose the type of car we were seeking. Once we knew what we wanted Filipo and Joe went out and found us exactly what we wanted as it wasn't on the lot at the time. I am happy to say that car is still on the road, being driven daily, and serving us well. We have since purchased 2 more cars, including one just yesterday, and couldn't be happier with the service and attention to detail the whole team there gives us everytime we walk through the door.
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

Great Customer Service
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.
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.
