Engine repair service near Sterling, MA

I want to preface my review by saying that the techs are very talented and I deeply appreciate the work they specifically did. I also would like to say Jake is an incredibly nice individual who does the best he can with what he is given, and unfortunately his colleague does not share the same sentiment. Rico lied about every facet of the job. From price, to estimated time, to simply what they would actually be able to do for me. He also made it very clear he did not respect my input and opinions even though I am the owner of the vehicle; I have my own opinion as to why he felt that way as well. INCREDIBLY upsetting experience considering my family is return customers of Zaks (I personally will not be returning). I again thank Jake and the techs for their diligent, and honest, work; And all they did in the face of their teammate actively working against them. Unfortunately, they can only do so much when the bridge has already been burned.

Had them "build" an EJ25 subaru motor for me not long ago. After 3k miles it is burning 1qt every 3k miles, and visibly smokes in boost and on decel. Alex assured me "the motor isn't broken in yet" at 2k miles. Its only gotten worse and I just continue to get run in circles. Don't go here to get an engine "assembled" go somewhere that's actually going to BUILD it and stand behind it. A few dynos and 300 facebook reviews totaling 4.9 stars is very capable of fooling your wallet!

Had problems with previous shops. Car always pulled after alignment. After visiting Atech the problem no longer exists. Very pleased! Super clean shop, very professional!

I love this place! My husband and I bring our Toyotas here for all services. They are fair, fast and kind. I love that they are a family owned business and treat their customers the same. We will be back! -Dawn

I found Paul through a recommendation of a friend. As a loyal BMW owner for many years, and one who babies my car and want to make sure it's got the best care, I was really happy to find Paul. He is not only a BMW owner, but knows these cars inside and out. I had a heating system issue, we spoke about it over the phone twice, he ordered more parts than needed so when I brought it in he had the correct part (regulator) on him and fixed it within an hour. He simply returned the part that was not needed. I was able to get work done in the waiting room (with wifi) and when I recently had another issue (cracked rim), he quickly diagnosed the problem too. It's great to find a mechanic I can trust AND who is reasonable (I priced him about against another non-dealer BMW mechanic and he was a bit cheaper!). Thanks Paul for your help and care. When my car is in need of service again I'll certainly be back!

Went in for a basic oil change and got charged for an upgraded one. The guy behind the counter was very rude. He talked down to me really bad he should not be in customer service!!. I will not be returning there again!
