I had posted a similiar issue last week. I need to have my '87 260E a/c charged. And i do plan to stick with r12 since everyone i've had a quote from so far are asking around $1000 or so to do the conversion. No one wants to do it without converting since they all claim that R12 is no longer available. And the one person who does have it said he'll have to evacuate all of the old R12 and fill it back in which will cost me around $400. I live in NJ. and would like to know if anyone knows of a good mech/shop where I can get my A/C charged without spending $400 to $1000 and stick to the R12 type ?
