I Was Wondering If There Is Anyone In NYC With A Mechanic Shop That Specializes In Diagnostics And Repairs Of Chevy And GMC Trucks? When I Say "Specializes In" I Mean A Shop That Pretty Much Knows Everything About And Can Repair Just About Anything On Your Truck. I'm Very Selective About Who I Let Touch My Vehicles And Thought Knowledge Of Any Specialty Shops Would Be Helpful. I'm Still Fairly New To The Chevy/GMC Family And Don't Know Anyone Who Works Primarily On Them. If Anyone Can Point Me In The Direction I'd Greatly Appreciate It. If There Is A Link That Has This Info Pleas Copy & Paste In The Comments. Thank You Again Everyone
