(Above reply possibly wrt my comment about engine size & emission)

When I called Air Care, I was looking for one set of numbers 
applicable to all cars manufactured in 1992. The "technician" who
answered the phone told me that this wasn't the case, and that the
maximum allowable changed with engine size. He required specific
model information, including engine size, before he could tell me
it's emission requirements. 

Without knowing more about the measurement technique employed
by Air Care, it's impossible to comment further on the validity of
the above statements.

The Vancouver Sun, some weeks ago, described how the owner of
an ancient Volvo passed the Air Care test with absurdly low
emissions. He had a hole in his exhaust between the engine and the 
tail pipe. Needless to say, this man has managed to insure his car for
another year.
