Donnie K is the way to go! I bought a Jeep Patriot last year from Donnie K after he came highly recommended from my dad. Donnie was very friendly, not pushy whatsoever, got me a I bought a Jeep Patriot last year from Donnie K after he came highly recommended from my dad. Donnie was very friendly, not pushy whatsoever, got me a great deal on a new Jeep, and didn't try to sell me anything extra that I didn't need or want. The process was easy and painless, because Donnie does what is best for the customer. As long as he is selling cars, I'd never buy from anyone else! More

Donnie Kostecki: Started As A Salesman, Ended Up A Friend I met Donnie the day I went in to look at 2014 Grand Cherokees last July - He was extremely knowledgeable and easy to talk to and ask questions. I had I met Donnie the day I went in to look at 2014 Grand Cherokees last July - He was extremely knowledgeable and easy to talk to and ask questions. I had been looking for a car for over a year and had never bought new- so I had a lot of questions and doubts. Donnie was patient and not the least bit pushy- I ended up going home with the best car for my family and career- and am so happy with it over a year later. Anytime I have questions, Donnie gave me his personal cell phone number to call or text! and he gets back to me immediately with answers. As if I didn't list enough of Donnie's wonderful characteristics - I have to mention one other story: I volunteer for Special Olympics Chicago and our biggest event is the Polar Plunge at North Ave Beach. This past winter, the day after the Polar Plunge, I was in the dealership for a nail in my tire, and who do I see walking the floor with a Polar Plunge hoodie on, Donne Kostecki. Turned out he jumped into Lake Michigan dressed as Batman in nearly zero degrees to raise money for Special Olympic Athletes, like my brother. What. A. Guy. If you're going to buy a car- this is the man who can help you and you will leave with a great vehicle AND a new friend, like I did! More

Donnie Kostecki rocks I really hate car buying and wasn't looking forward to the whole ordeal when we needed to replace our car. But my wife and I went to Sherman Dodge to I really hate car buying and wasn't looking forward to the whole ordeal when we needed to replace our car. But my wife and I went to Sherman Dodge to see Donnie Kostecki on the recommendation of a friend. Donnie was straight up and honest with us and helped us to buy a brand new car. We also weren't really sure what kind I car was best for our needs and he showed us a Dodge Journey which we had not thought about before. It was a good alternative to our old Dosge Durango that for like 15 miles a gallon because it for our whole family and got much much much better gas mileage. I would have never thought about a journey, but I'm really glad that Donnie pointed us in that direction. Next time I buy a car it will be from Donnie Kostecki. More

Best sales experience. We have been customers of Sherman Dodge for years purchasing 3 cars and bringing all of our service work to the dealership. When I mentioned to a We have been customers of Sherman Dodge for years purchasing 3 cars and bringing all of our service work to the dealership. When I mentioned to a co-worker that I was taking my sister to Sherman Dodge to purchase a Jeep Cherokee, he recommended that I talk to Donald Kostecki.. I had never met Donald before but was impressed by his knowledge, professionalism and his customer service. My sister purchased the car. We decided to purchase the same car a week later and called Donald. Some friends were looking for cars for their children and at our recommendation about Donald purchased 2 cars and told us they would also recommend him. When you meet a personable professional like Donald, he is the salesman you talk to. More
