My dad has a 1987 300E with 160,000 miles on it. He had it converted to r-134a because the r-12 had leaked out. The mechanic put dye into it I think like 3 weeks ago and now the freon has leeked out. While it was working though it didn't seem to be as cold as "normal" american cars. But, I was wondering if the A/C on these cars is even very good anyways. (stock/converted to r-134a). Would it compare to an American car's A/C? I was just curious, that's all.
Thanks
David
