What's the final word on the 190E AC unit. I've looked at about 15 various models to buy (84 - 87) and only one had AC that worked (unfortunately the tranny went out the day I test drove it!!). I guess the question is what is the typical repair (refrig or compressor) and the typical repair costs. I like these cars but the AC prob is keeping me from buying some nice vehicles because I can't seem to get a clear pic of the topside costs. Thanks.
