Diagnostic services service near Cornwall, NY

Jeet is professional and extremely efficient

I have been using Sierra Auto for over 15 years. The tech (Johnny Jr.) is a ASE master tech. Really knows his stuff. They were always able to work out pricing from day one. They also stand behind their work. I would recommend them any day.

Very happy, job done right and price was fair.

Scott is a fantastic auto mechanic! So thankful i found this shop. Scott diagnosed my honda element and isolated the transmission problem. He backed me up and got honda to install a new transmission for free. I am forever a THE GARAGE customer and tell all my friends and family.
