Emissions Test

Just search around for a shop that will do the right thing. The first shop didn't do him any favors by failing him, now his VIN is in the system and Big Brother is watching.
I used to conduct NY state emissions inspections in the 80s and 90s, when tolerances were unreasonable and the state had a video camera watching over the bay.
I was able to wiggle results then, I'm sure it can be done today.
Ya know, a few limited use classic cars aren't gonna amount to much CO or HCs in this world.
