Just want to find out if my 1990 uses R-12. Found a can on Craig's --28lb for $240. My A\C blows a little warm. thanks

Originally - yes.

Now - depends. Look at the ports. If you see threads, it should be R12, If it's a quick disconnect, it's converted to R134a.

Don't forget to fix the leak if that's what it is, or you'll just end up having to hunt down more R-12 before you know it.

I have to look at the ports--are these prone to leak in any specific area?

It must have been converted. Quick disconnect under the cap near the compressor. thanks for the info

in which year did the w124 come with a 134a system from the factory?

134 became mandatory in 94
not sure what year MB put it into service.
I should say that 12 not in the car was mandatory in 94... I don't suppose they cared what you put in as an alternative...
