All trade values are not final offers, just estimates. Final offers are subject to change based on the used car market and specific vehicle history. We will not be able to provide a final offer to you until we physically see, and test drive your vehicleRetired Courtesy Vehicles sold to the end user, are being sold as used cars, yet, they may qualify for most of the new car sales programs posted by the manufacturer in the month of sale. The vehicles are being sold at a special lowered price point to compensate for the miles driven, the shortened duration of the new vehicle limited warranty and for existing wear and tear. Prior sale, the vehicles are inspected and reconditioned to an almost new condition. Despite this fact, certain minor wear marks, chips or minor scratches on the exterior and the interior of the vehicle are considered acceptable and cannot be undone without extra cost to the end-user. These vehicles are subject to prior sale or might not be available for immediate delivery. Since these vehicles might be currently in use please call one of our sales team to ensure the vehicle is available for a test drive. Click an image below to view more vehicle details. These vehicles are currently being used or have been used as service loaners, all have incredibly low-mileage, and were driven by our greater Chicago area clients while their vehicle received service.

Great car
By Robert | on Sunday, December 04, 2022
Powerful yet comfortable coupe that has great looks. No mechanical problems in 30k miles. Mileage around town 20.5 summer 21.5 winter. Never have taken rear passengers, too small back seat.… - 5.0
2019 M850i
By Tony | on Monday, August 14, 2023
I have been driving this car for a while now and I am about to hit 50k miles soon. Not one single issue ever, just maintenance so far and even that was relatively cheap. The sound this V8 makes is just something you'll never get tired of. I sure haven't. the XDrive system really makes you feel all of the torque when you launch it, amazes me every time. MPGs are pretty darn good too for its size and power. The ONLY downside I have with this car is its tire profile, its very easy to get tire damage if you have the 19+ inch size rims. Other than that, it's an awesome vehicle.… - 5.0
Perfect Grand Tourer
By hopdoddy | on Sunday, September 25, 2022
840i, everything is excellent and works as it should, great ride, handling, balanced performance, enough power, gas mileage, if you and one other person want to take a trip in perfect comfort in a car that is a pleasure to be in, this is it. Holds enough baggage, good fuel mileage, really fun to drive, beautiful well thought our interior, all the bells and whistles. When I think of this car, the word "Balance" comes to mine. Enough power, great handling, excellent ride in a quiet, well appointed interior, not many of them on the road, I just feel at peace in this car. IMHO this is the ultimate expression of an ICE vehicle, it is the representation of the end of an era, and checks all the boxes. Get the 840i, stay out of the pricier V8s and convertibles, and just enjoy!…
