#288859 They really do emissions in your state for cars that old? Ours is all visual. Even if your check engine light is on

#288862 yeah im leaning towards the car for sure. Yeah Ohio is stupid they only do smog check in 6 or 7 of the counties in the whole state and the car has to be older than 25yrs old for it not to be done.
