Used Mercedes-Benz GLS 450 for sale near University Park, IL under $899,990

I bought a 2021 Mustang Mach E for my son and I thought it would be more complicated getting the $4000 rebate but it ended up taking 2 minutes. Highly recommend if you are trying to get the IRS rebate on EV’s.

This car met all my needs and more. Love the interior and the way its moves. So comfortable and reliable! Very pleased with this car!

We recently purchased a 2025 C300 4Matic from Romeoville MB, and the experience was outstanding from start to finish. Jayda and the entire staff were incredibly courteous, knowledgeable, and helpful throughout the process. They made everything smooth and stress-free. Highly recommend Romeoville MB for anyone looking for a Mercedes-Benz vehicle and top-tier customer service!

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..

Agnes was beyond amazing!!! She was so personable, helpful, and friendly!!!! We drove almost 3 hours to buy our new Land Rover and we would most definitely return to work with Agnes ANY TIME!!!

My 2 honest cents. Just bought the 2024 GLS 450 and it has a huge presence on road and it looks stunning! I went with the AMG exterior package and it looks way better than the base model. Ride quality is good, very smooth ride on freeways but you do feel small bumps on occasional city roads. The engine is good but I wish it had a bit more power, feels little laggy at low speeds but when you floor it it moves fast and steering is very responsive. On the other hand, cabin very silent tho and you barely get to hear road noise (without acoustic package). The Mileage is incredible on this, wasn't expecting to write about it but the GLS gives better mileage than my GLC. Interiors are amazing and is something no other manufacturer in this segment can match (especially at night with ambient lights), seats are super comfy and the infotainment screens are also crisp. Overall, love this SUV and i'm gonna keep it for a while.

Just took delivery of my second purchase from Ultimo in 4 and a half years. Both times they treated me with respect and transparency. Their service department is easy to work with as well. I live out of state but visit the area quite often due to work and every time I am in I get my maintenance service done there as my local Mercedes dealer charges an arm and a leg even for an oil change. I can say they have a lifelong customer in me. Highly recommend their sales department, Alan, Tash, Chris. Sean in finance is easy and helpful and Nick in service as well. They all treat me like I am part of their team even though I am just another customer from 2 states over.

Very happy with my purchase from RBM Alpharetta. The car has a very comfortable interior with all the features available. Handles well in town and on long drives. Good acceleration for such a big vehicle. Love the contemporary exterior.
