Great experience with John and Florin.
Great experience with John and Florin. They know their stuff which made this transaction stress free.
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.

Autos of Chicago provided excellent customer service from
Autos of Chicago provided excellent customer service from start to finish. The staff listened carefully to what I was looking for and showed me several great options. They were honest, patient, and never made me feel pressured. The car was in excellent shape and priced fairly. The paperwork was handled efficiently, making the entire experience stress-free. I highly recommend Autos of Chicago to anyone.
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!

The whole dealership is great. I've purchased several Hondas at Motorwerks and no matter how hard I try to find a new brand to drive, I come back to Honda because of Motorwerks. Kacper, my salesman, was very helpful too.

I recently bought a 2026 CRV and absolutely loved my experience at Zeigler! Victor Cortez made the process quick and painless. He was extremely helpful and you could tell he truly loved the product he was selling! Jovin Kalappurackal was great during the finance portion of the process as well! Super knowledge, explained everything clearly, and answered any questions I had! This was one of the best car dealership experiences I have had. I cannot recommend them enough!

Had an excellent experience of Fields Mini.
Had an excellent experience of Fields Mini. My Salesman, Joe Salgan, was extremely helpful in helping get the right vehicle at a fair price, working through the logistics of delivery and trade-in, and setting up and explaining the features of the car. Also, the financing people were very professional, fast, and accommodating in getting the docs signed. s
