I own two 124 cars - one with R-12, the other with factory R-134a. The R-134a car actually has much better air conditioning - it cools down faster and stays much cooler in stop-and-go traffic. I agree with Paul, the 1993 has one of the more powerful a/c systems I've experienced.

The condensers between the two cars are not identical. However, only the connections for the refrigerant input/output are different. The condensers themselves are pretty much identical in terms of size, design, and construction. So it appears the factory did not radically change the condenser design when converting to R-134a.
