If you're talking about R-12 vs R-134a, R134a is not an upgrade over R-12. That's a stupidity lazy shops perpetuate to do less work. If you want the best performance from your AC, stick to the refrigerant is was designed for.

R-12 is still available to recharge your system but you have to look for someone who won't insist on switching to R134a. If it came with R134a, anyone can recharge it. Heck, you can do it yourself.

The 190e's in NA were R12 as far as I know.

It's nice to see some good advise.
But you do need to find the leaK FIRST BEFORE YOU CHARGE YOUR SYSTEM. If you want a reliable system for the next two to three years, plan on spending a grand. Not saying you are going to have to, but plan on it. You wont have to worrie about it for a while.

There should be a sticker by the radiator that tells you whether you have R12 or 134. I agree if you have R12 stick with it - it's a little more efficient and still widely available although at a higher cost. The system probably takes about 2 lbs, the sticker will say.
