I had a great experience buying my tesla from highline
I had a great experience buying my tesla from highline auto sales, specifically Scott. We were able to talk and text to negotiate a price both for the car I was buying, and the car I was selling. When I came in to test drive the vehicle, the car operated as expected. Once we got to the buying process, I was in and out of there in 45 minutes, with all the documents signed, and highline stuck to their word on the price we agreed upon on the phone. It was a flawless experience. Highly recommend them for a used tesla.
very roomy and functional
I have test drive the range rover the X7 and I find this is the best for me , it has the room and comfort plus all the safety plenty of power too with a good mileage for a car this size .

Large yet stylish enough to carpool the Grands
We just bought this car. Comfortable, roomy, easy to drive. Not quite a luxury ride that the Lexus GL has but performs well. Takes a second to get comfortable with the bells and whistles. Beautiful car, 2 2 2 seating. Easy for kids to get in without climbing over or moving a seat. We bought this SUV for me to drive around town as well as to school carpool my grandchildren. So far...very pleased. This is my third Mercedes. My only complaint with Mercedes is the fuel tank on the passenger side. I feel a little more vulnerable being on the opposite side of the driver side when pumping fuel. I assume it has been this way for years. I guess safety at the gas station was not as big of a concern as it is today. If considering a luxury SUV test drive. I think you will be pleased/

Hello I recently purchased a MB CLE 53 virtually from MB
Hello I recently purchased a MB CLE 53 virtually from MB Naperville. I had never purchased a car w/o being present and I can say that the MB Naperville team made the process seamless and straightforward. My main sales contact Ron Genot was extremely helpful and his ongoing communication and updates was much appreciated during the sales process. Very Satisfied. M Lindsay

I was skeptical about purchasing a car from a used car dealer however in having very good experience in purchasing a new BMW from Perillo BMW many years ago the Perillo name provided me some comfort. Perillo Downers Grove delivered upon my expectation’s in purchasing a lightly used BMW 750i

“GREAT EXPERIENCE”
Salesman was very personable and friendly when my wife and I visited the dealership. The finance person was very friendly and very helpful when we needed financing the auto purchased. They both were better than the average dealer staff and I will buy my next auto from this place. The experience there was very easy and pleasant and I will highly recommend this dealership to anyone considering the purchase of there next auto.
