2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Jose was very nice and personable and was willing to explain the process and answer any questions I had. The vehicle was everything I was looking for as well.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

trustworthy for life
A friend recommended Chignoli to me for a used car. He has bought all his cars from them for decades. Now, I plan to buy all my cars from them from now on. They don't push you to buy. They ask what you are looking for, and your price range. They listen. Then, if they don't have it on the lot, they go hunting for what you want. They won't sell you a cheap lemon. And they offer a solid warranty. Our family bought two used cars from them in the past two years. Both run great. We couldn't be happier.
Great vehicle
This car has everything technology offers in it plus more. The feel of this vehicle is extremely smooth snd quiet. One of the best purchases of ever made. I’m extremely pleased and love it

Great prices good service very polite and knowledgeable staff. I bought a car from used car super store. After being tricked by lots of dealers and sales guys I was referred to them by a fiend of mine and I am glad I did go there and ended up buying a car. Very honest and straightforward sales staff.
