I'm old school, I just don't like change, lol
John M,
Yeah... actually... I know exactly what you mean. I was working as a mechanic in the late 90s, when R134A was brand-new (where I went to school for it), and again in the late 00s (down here in Tejas) when everybody and his grandmother down here thought you could just screw a couple fittings on your R-12 clunker and refill it from a spray can and it was "retrofit".
You have no idea how many $1400-2000 estimates I wrote up to fix "my dumba** brother's screwups". Good thing the shop had financing.
The really bad part is... at first the car manufacturers REALLY didn't know how to work with R134A either; there were a number of OEM systems that NEVER worked right straight from the factory because, as we know, many decisions on the assembly line are made by "Management" rather than "Qualified Engineers". The mid-to-late 90s were a nightmare of incorrectly mixed parts, especially from GM and Chrysler. Saturn was actually the first GM line to get it right cuz they started out with young engineers who were designing with R134A in mind, rather than reverse-engineered R12 systems.

RIP, Saturn. You were the best of GM; that's why you had to be sacrificed on the altar of Corporate Greed.
