Meet One & Only®, Exclusively at Mercedes-Benz of Barrington, the only way you will ever want to buy or lease a vehicle ever again.
Only One Price:
All vehicles clearly display our Market-Based Price. This is done to save you time and eliminate the traditional back and forth. It’s very transparent and helps to expedite the process.
Only One Person:
You will be working directly with just one person, a dedicated non-commissioned Client Advisor, whose only goal is to provide you with a relaxed and stress-free experience.
*Only One Hour:
Since only one person will be helping you with everything, it will all be incredibly fast. No more spending the whole day at the dealership. Once you have selected your vehicle, will have you on the road in about an hour.
