I don't think any of our cars were A/C in the 50's and 60's ('56 Ford, '50 Chevy, '47 Plymouth), and my first car with AC was in 1997 with a Dodge Neon. Tell the truth, it's not really necessary most of the year around here, until one ventures into the eastern valleys. Nice to have to get condensation away from windshield, though. Since then the AC on the Neon has lived up to its built-to-a-price heritage, and the refrigerant seems to leak out every few months. Not a big deal since it's been parked waiting for a new rear main seal.
