Love the car only had a coolant pump issue but ever since
Love the car only had a coolant pump issue but ever since it's been smooth sailing. The car is gorgeous and incredibly comfortable with beautifully designed interiors. I've drive both the Mercedes c43 Amg and the bmw 340i which I think are this car's competition and I'd still have this as my overall pic.

Bryce took care of me in no time at all, great car and price! Thank you!!! Will recommend to everyone!
STUNNING MACHINE S5 Cabriolet
I can write an entire diatribe about this car but I'll keep it simple! If you are looking for a luxury, convertible, look no further than the S5 cabriolet. I looked at the C43, M440i, this car, IMO, is the BEST value for the money! It is an absolute beast in the performance department, the options that come with this car for the price are unmatched and of course every single detail is perfectly executed!

We had an excellent experience working with David M!
We had an excellent experience working with David M! He is knowledgeable about the different Crv models we wanted to test drive and compare. Schaumburg Honda's wide inventory of the various models also helped us make our decision. David went above and beyond when it came showing us all the unique features of the vehicles. He also made trading in our Honda Civic and switching our plates an easy and painless experience.

Smooth and Easy
Though I intended to purchase a used vehicle with a much lower sticker value than most of the cars on the lot I was treated with utmost respect and friendliness, from the office staff to the mechanic to one of the partners. They understood we had driven a couple hours amidst the coronavirus pandemic and worked quickly and easily with me to take the car home that evening. They honored the out the door price we had discussed prior to arrival and even shipped parts they were unable to return to Toyota at no cost to me.
Love this car
This is an S5 convertible and it is a blast to drive. Plenty of power, great interior and is great with the top down. I love Audi's and enjoy driving them.

Thumbs up to Casey!
I recently had the experience of working with Casey to purchase a new car at Rochester VW. I have bought many new cars and I would like to say that this was the easiest purchase I have ever had. Casey did everything she could to make sure I got the car I wanted. I will definitely refer her to friends when they are looking to purchase a new car. Thank you Casey for being the BEST sales person ever!!

Trustworthy | Honest | Professional. Some of the best customer service I have ever seen from any business. They went above and beyond to make sure I was able to purchase the pickup I wanted. I was traveling from out of state and they were able to take a deposit to hold the vehicle, kept great communication throughout the process and literally pick me up from the airport. I am beyond impressed with the kindness of this team, you're lucky if you get to do business with them.

We went on the evening of June 24, 2025 to look at a vehicle on the lot, and we ended up purchasing a 2022 Hyundai Palisade. Our sales rep, Austyn Long, was phenomenal. We never once felt pushed or forced on anything. He was great to work with. What won me over was my wife was backtracking as this was a very large purchase, and not once did he try to push the sale. He gave a few words of wisdom and backed off. As long as he stays employed there, he will probably have customers for life.

Yesterday I purchased a car by phone for the first time.
Yesterday I purchased a car by phone for the first time. As a senior citizen I sold my car on the 9th of March thinking I would get totally travel by taxi or Uber or Lyft but I under estimated the value of getting up and going when you like. The team at CarMax from beginning to directions to the highway were the very best. Each and every member made me feel valued as a customer. And feel like they were treating me like they would their family members. You could not ask for more than that. Bj
