When did DEF become required ?
Thinking of upgrading to a DP. I want to avoid having to deal with DEF. What year models did it become a requirement ?

Do not know about Cats.. Never researched them to see how much good they do.
I have a 1964 car with no CAT and no seatbelts that I have owned for 16 yrs..... the good ole days. The automatic windows work without the key and you can change the gears (no column lock).
And, let me say, I can't leave that car running in the garage for 5 seconds without smelling the effects of no CAT (6.25 liter V-8).
