Actually, by 1996 all vehicles in the US must be OBDII compliant.  The 
Clean Air Act of 1990 will allow the EPA to accept Califormia systems 
through 1998.  So OBDII is required by 1996 but if the manufacturer can't 
make it they must at least meet California requirements through 1998 when 
California and OBDII requirements are identical.

It should be noted that the LT1 Corvette and 3.8L Buick Regal were OBDII 
compliant as of MY 1994.  The only thing these cars don't do is enable 
the malfunction indicator lamp (MIL), or another "Check Engine" light.  
They do store the codes in memory though, so a technician with the TECH 1 
can read the faults.  For 1995, the 4.3L GMC Sonoma/Jimmy and Chev 
S-10/S-10 Blazers are fully OBDII compliant.  Also the 2.3L Quad 4's in 
the new Cavaliers and Pont. Sunfires should be fully OBDII compliant.  
Finally, the 1995 Camaro's and Firebird's should be fully OBDII 
compliant.  

I am not sure about any companies other than GM but I would think that at 
least Ford would probably have a couple vehicles out there with OBDII as 
well.
