looks good, although this time year is kinda of bad time to not have a working climate control. if you do get the car I do have documents I can send you to help in diagnosis. I just diagnosed a non operational w126 climate control problem. 2000 is about right. keep in mind the 126 climate control is much more involved than the w123 chassis.
