Same day service for belts and spark plugs. In and out the door fast. I even went to the wrong branch and was still served! Wonderfully efficient.

Staff were all kind helpful and very professional The staff allowed me time to look at a car. Price was very competitive
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.

Not a review writer, but had to share the great
Not a review writer, but had to share the great experience. Went to multiple dealers and left frustrated with lack of willingness to deal or even return a call. This was not the case with Chicago auto place. Robert made the whole transaction super simple with zero pressure. Car needed a few small items and he took care of them with out question and had the car ready a day before I was expecting it. Robert was able to match my private bank low APR. Of the 15 cars I’ve purchased this was by far the best experience. Highly recommend.

Very pleasant atmosphere and the hard working staff that makes it all happen service advisors, service technicians, parts department, billing dept. and cashiers, & sales and to add that I have a quite long history with Roesch i can honestly say that all though i had one bad experience with the service department that was swiftly rectified by means of the service manager overall I would recommend Roesch dealership to any of my family members and associates , lastly I must say kudos to service advisor ( Jessica Mamahua ) & service director ( Adam Jaswilko ).

Really nice experience purchasing a vehicle at Motor
Really nice experience purchasing a vehicle at Motor Werks. I have bought two other vehicles from them in the past and I drove each for 10+ years. Hoping this new Honda CR-V EX-L does the same. Motor Werks has a nice inventory to choose from. The sales staff is amazing.

I have bought many cars and my last experience at Motor Werks Infinity was definitely one of the better ones. Bought a used 5 series from John Gregory, he was very professional, got the car on the lift for me to see, had it fully detailed and full tank of gas.
