The ac ran cold and under the hood was very clean but I expected it to be given the appearance of the rest of the vehicle. I haven't spent a lot of time under the hood of this car yet so I don't know yet the age of some or most parts but my guess is largely original. It's been in this family since new, the wife has had it now for the last year and a half after a divorce. She did little to it other than brakes and tires while she had it on her own, now it just sits in the garage. She can tell me what was done to the car from memory but they have no paper trail.
