 Trustindex verifies that the original source of the review is Google. I found Andrew and his shop via a personal recommendation and they were right he does outstanding work reasonable prices and able to explain things in a very precise and concise way. I used to go to the Mercedes-Benz dealer but felt like I was being taken advantage of and worked that should have been done wasn't and stuff that was done shouldn't have been done at least not then. I'm in the health care field and have been practicing anesthesia for over 39 years. We are both in the service-based industry and I can tell you that Andrew goes above and beyond when it comes to maintaining and taking care of my vehicles all four of them

 Trustindex verifies that the original source of the review is Google. I brought my 2017 Benz metris here for a coolant drain and radiator drain with new gasket and filter he fixed that and then found my serpentine belt was bad though he had another car to fix he replaced my belt seeing that I was going to travel out of state very much appreciated and is a very nice guy. I will definitely be back for service again.

 Trustindex verifies that the original source of the review is Google. I brought my BMW in to have it serviced after getting a quote over the phone. Andrew was clear with his pricing and sent updates and pictures throughout the process. Honest work is hard to find but if you come here you will have found it. Thanks Andrew I will be spreading the word! Highly recommended.

 Trustindex verifies that the original source of the review is Google. Andrew is the best mechanic I’ve taken my car to. He kept me updated throughout the entire process, & he’s probably the only honest mechanic I’ve dealt with. The work was done earlier than anticipated & was done beautifully. Will definitely only be working with him for any future repairs. I’d give him 10+ stars if I could.

Thank you again Andrew!

 Trustindex verifies that the original source of the review is Google. Andrew came in clutch. I was stuck at the mall and he came in 30 minutes to help me start my car again. After starting it, he fixed the problem at his shop and I was out as scheduled. Fast, efficient, and beyond reasonably with a one stop shop.

 Trustindex verifies that the original source of the review is Google. Jankowski Import Auto is by far the BEST!  I have not ever had the pleasure of dealing with a mechanical expert with such a high level of knowledge, preciseness, and great customer care!  Andrew Jankowski is truly an EXPERT and that's putting it lightly.

This gentleman truly knows his stuff and he is above and beyond what you could ever imagine.  He filled me in every step of the way regarding my repairs which I have not ever experienced before either.  Not to mention my repairs were completed in a very timely manner.  I will not ever take my Mercedes anywhere else!   No more dealerships.

First Class!  A+!  Professional!   Thank You Andrew I will see you when it's time for my next service.
