In the uk definately, and would of thought the world realy, i have a golf gti 92 without a cat (just missed) and a 93 uno cat equiped (even tho i unequiped it) didn't every car manufacturer move over to tighter emmissions eg cats in 92 i always thought so maybe not? ant!
Pretty much all new cars sold in NZ will have emissions and cats etc but its not required by law. The only emission law is, and I quote. "vehicles must not be too smokey" bahaha!
With European stuff, we mostly get UK market cars. However a friend has a 1993 Uno turbo (the only one in NZ) and its the same as my 90, no emissions.
