New and used 2026 Mercedes-Benz C-Class for sale near Upper St. Clair, PA

Mercedes Benz of Washington (PA) diagnosed and fixed a problem another MB dealership caused. From the moment I walked in the door I knew I was in good hands with service writer Amy Nelson. I did not have an appointment for a Service B but Amy quickly got me in and arranged for a driver (Dale! Who was awesome!) to take me back to my office. A problem was found under the hood that only the MB dealership where I purchased the car could have caused. This is where Service Manager Bob Anderson came in. Bob went above and beyond to get my car properly fixed and out the door in record time. Come to find Bob has been at this dealership for 35 years. Unheard of these days! Bob and staff provided me with the utmost care and for that I am most thankful.

Mark the salesperson went above and beyond in our purchase. This is the second car we have purchased from Mark in 3 or 4 weeks.You cant go wrong with these people Thanks Mark for the great experience

Tess was outstanding in helping me find the exterior and interior color scheme of my vehicle, along with the great price! She made the process of purchasing a car go smoothly.

Had precise vehicle desired. Delivery on our schedule. Provided offer of follow-up for maintenance. Car beautiful upon delivery. Would consider buying again. Promised to retain on mailing list.

This dealership was the first of many that we visited searching for our next vehicle. Upon entering the building, we were happily greeted by Omeed Safagar. He was courteous, attentive to our needs, and was not pushy. What impressed us is that he sat in the car and showed us every detail from the passenger's side all the way around to the driver's side, to the cabin and cargo section of the car. He not only answered every single question, but he displayed knowledge about every feature. In contrast, every other dealership either made us wait to be seen, did not know about every feature of their car and "glossed over" their answers, and even one ended our visit abruptly to cater to another guest. The manager, Stephen Staats, was also a part of the experience and even predicted that we would be back. We laughed at the time, but he was right! The sales process was fantastic, and we highly recommend asking for Omeed if you are planning on visiting this dealership. We are very happy with our purchase and hope that the rest of our experience there is just as positive.

Minneapolis: 3AM: Awake, Can’t sleep. Doom scrolling nationwide for a new Mercedes, and after being dismissed by my local Mercedes dealers, I found the car I wanted at Sisson Mercedes in Washington, Pennsylvania. Filled out the “I’m Interested” tab, not expecting to hear anything back, and a few hours later…It was 3AM after all…I got an e-mail from Kristin Presutti at Sisson Mercedes about the car I was interested in…Being we are both Italian, She made me an offer I couldn’t refuse and I now await my new Mercedes to arrive in Minneapolis from the suburbs of Pittsburgh. It’s now days later and I have yet to hear from my local Mercedes dealers…I have been buying cars since 1979 and Kristin is truly the best salesperson I have ever dealt with. I cannot recommend her highly enough. Simply outstanding.

I have bought a lot of cars in my life and this was, without a doubt, the best experience ever. Exactly the right amount of attention.

If you decided to purchase a Mercedes Benz, go to Bobby Rahal in Wexford and ask for Kris Kurtz. Kris knows Mercedes Benz and comfortably walks you through the process. No pressure, he just deals in facts. It was a pleasure working with Kris on our purchase of a new C 300. Could not be happier with our experience with Kris.

First class experience from beginning to end! Can’t recommend Bobby Rahal and our salesman, Brandon Zappi, enough! No pressure, no hype, just great salesmanship. We were very impressed with every aspect of the sales process, especially the presentation with the big red bow! It made this special occasion even more memorable. The staff at Bobby Rahal are friendly and knowledgeable and really put us at ease. We can’t recommend them enough! They are simply The Best!!!

I had a great experience at this dealership. Very professional and such a fast reply , also the manager followed up to make sure I was happy. I will be recommending this dealer to my family and friends.

Even though I did not buy the vehicle I went to look at, I was treated with the utmost respect by the dealership and Chris, the salesman who worked with me. You can definitely tell the difference between sales people when you go to a Mercedes Benz dealership! I only wish they could have certified the Subaru Ascent I looked at because it was really a great deal. When I look for my next vehicle, it will include looking at Mercedes Benz because the cars they had were stellar! Just not the right time this time! Thanks for the experience!

Bought a beautiful pre owned CL550 from 900 miles away!! Darien Lux took care of everything and kept me extremely satisfied. What a wonderful purchase experience Mercedes Benz of Pittsburgh provided. Thank you Darien Lux.
