Value of an entire a/c system?
 

I had mentioned to my mechanic that I was thinking of getting rid of the A/C compressor in my car. He said that he had another customer that was looking for an original A/C system, to include the front and rear condensers. He asked me to think about it and if I wanted to be the donor vehicle, to let him know and he would work out some numbers.
So, since this is the first time I have owned a car that had desired components on it, anyone venture to guess what an entire original A/C system (functioning), would be worth?
