My AC just quit a few days ago (its a 87 190E, about 112 K miles). Have had no problems with the AC before. Went to a local guy today - he says the compressor is seized up (450 + 3 hours labor), freon needs to be charged up ($200), plus, the expansion valve may need to be changed (can't tell till he opens it up, another $200), plus some filter in the front may need to be changed. All in all, at least $800, may be upto $1200. Is he quoting me a reasonable price, or am I being taken for a ride? I can't spend a thousand bucks on this old car now, especially for the AC, which I use maybe 2 months a year.
