Twenty First Century Dignstic 700 South Country Road, East Patchogue, NY 11772

"Kevin and James are two reliable honest compassionate caring people. My mom gets her car serviced with them (I will be now and all my family and friends) and they have never steered her wrong. They take their time to diagnose and give a fair honest price. These two men will make 100 percent sure your vehicle is in working safe conditions before leaving their shop. They both have worked with my mother’s car who unfortunately is old and it’s time is just coming but we are just not in a financial situation at the moment to purchase another vehicle. I expressed my concerns to Kevin and he was honest about all that needed to be done the cost of it and what he would have fixed first as a priority he knew my budget and he knew how stressed I was as we only have my moms car at the moment and it was so important as she was undergoing chemo. They went above and beyond the impossible for my mother and I and didn’t stop until they had a safe reliable solution and I can’t thank them enough. This year has been a rough one and especially a rough one with the car and they never once made me feel like I was aggravating or bothering then in anyway. I could sit here all day and continue to write how great they are and how great their quality of work is but I will leave room for other clients to do so. With that being said Kevin thank you so very much for all the hard work you do and James thank you for all your hard work you do. You now have for life clients not only between my mother and I but my entire family and friends lol. The WALSH AND KOTSONIS FAMILY PATCHOGUE AND SHIRLEY NY"

"Honest & reliable. Super fair pricing and great mechanical work. Don’t waste your time trying to find other mechanics, the best ones are right here!!"

"Kevin and James are honest and reliable professionals who treat you like family from the moment you walk in the door. No surprise that they are always so busy, regardless they always get your car done without issue."

"Don’t waste your time looking elsewhere. I’ve been a customer for over 6 years now and have received nothing but great service. They kept my previous car alive until it just couldn’t go anymore lol. I now bring my current vehicle there for maintenance. My fiancé had some car problems recently and brought his car to a local mechanic by his home; He was told that the solution would be a $1,200 fix. I suggested that he go to my guys (Kevin &James) for a second opinion. Lo and behold the fix was a few hundred dollars. Saved my future hubby about $1,000!!!!! These guys are absolutely amazing! Very trustworthy, skilled, professional, and caring."
