Well my test drive went pretty well, but now I'm even more confused. 83 300d 147k---Car has a water leak problem. (versed in the threads covering this). No tach. Sunroof inoperative. Engine starts right up and idles smooth. R-134 ac is working from side vents not center. Vaccum line plugged for shut off fix. Transmission seems good, but had to throw it into 3rd to get power. Something not really tight in front suspension, but not bad. Paint is bad. Corrosion under back window seal. Bad fading on hood and top. No radio. Oil pressure pegged at 3 while driving slips to 1.5 with no acceleration. Few other rust spots. Checked blow-by after test drive. Continual puffing of light smoke visible during the day. Dirty, oily engine. Very uncomfortable front seat, but pleasantly surprised by legroom. (I am 6 foot seven). Owner is 6 foot 8 and has 2 other 123 300's in driveway. Owner says has owned car for two years. Just did complete brake job, changes own oil, transmission and ac service, but hasn't adjusted valves since he's owned it. Fairly adequate oil stains on driveway. Owner is asking 2500. I'm thinking 1000-1500. Your opinions are highly valued and appreciated.
