Okay. I finally broke down and had dye put in my A/C System.. mostly because I wanted working AC for this summer. My mechanic found out the leak was coming from the front seals of my compressor (The compressor works, but leaks heavily).. thus, it'll need a new one. He said with the cost of the new compressor, plus the R-12 and new pressure switches, etc.. it'd be "cheaper" for me to convert to 134a.. and gave me a estimate of $1,000. This seemed a bit high to me, since I know a new compressor is only 300-400 tops. (My car is gray market.. and the AC system was aftermarket. The compressor is a Volvo). Is this a fair deal? Or should I tell him to keep it R-12, and ask why he wanted so much? I know R-12 costs more, but $1,000 to convert it just doesn't seem worth it, to me.

Aside from that.. my 300D runs incredibly hot on the highway (110C). I asked him about it, and he found a ton of cold spots on the radiator. Turns out my radiator is pretty much shot (understandable for a 22 year old car). He quoted me $325 for the radiator, and 1.35 hours labor. The guy seems like a nice mechanic.. but these figures just seem a bit high to me. Maybe I'm just cheap..
