Eh. I think you are being a bit harsh..... compared to some, nanni seems to be doing OK. Plus, its his car and he seems perfectly able to do his own risk analysis on what he is doing. (unlike many others)

(I'll change my mind if he just slams in two cans of freon and say "blows cold now"... )

But I do understand the sentiment.

I will also acknowledge Nanni's poise in response....
