5-Star Review by Louis O

Even though I was only there for an Inspection, I found the entire experience from phone call to end of appointment very easy, convenient, and accommodating. The nice man at the desk was a pleasure to work with. The waiting room was very clean, impressive, and warm. I will be back.

5-Star Review by Joseph A Aiello Jr

These guys are the most professional and knowledgeable mechanics. I've been going there for over 25 years and was never disappointed once. They only have the best guys working there in that field. I strongly recommend them if you need a mechanic shop. I moved out of West Babylon over 10 years ago, I live 30 miles away and STILL go there!!! Thank you gentlemen for your outstanding service!!

5-Star Review by Doreen GIBSON

Cosmos has always provided reliable and courteous auto service.  Good communication with customer and updated appointment scheduling methods is a plus as well.  Would recommend to anyone needing auto services.

5-Star Review by Dee Jay

Went in for an NYS inspection and a oil change, they told me my front brakes were real low and my rear brakes were passable and could last a while. they also sent me photos showing me my break problem which I thought was a good business practice. They did the brake job in a short amount of time and at a reasonable price. A very friendly atmosphere and I will definitely be going back for more services to be done.

5-Star Review by Vince Vincent
