I realize I may be comparing apples to oranges, but I went thru a frustrating experience with a Honda Accord(R-12) about 4 yrs. ago.

Local shop told me everything needed to be replaced - $1500-$2000.

You mention the clutch doesn't engage. In my case, the system was dry due to a faulty low pressure switch. $45 for a new switch, $20 for a 609 cert. and 2 cans of juice and I was back on the road. 4 yrs. later, it blows 36F out the center vents on an upper 80's - low 90's day.

Do a little digging/studying before you unload your wallet.

My 2 cents.
