My 79 300td wagon had 345k fixed on its odometer .I bought it for $650 and sold it recently for $1500 or so .It was a great car and I drove it off and on for a year.I guess I put in another $400 in service ,mostly suspention,so I made out OK.My thoughts follow alot of what you guys have mentioned and I really do appriciate the inSITE .Their is a point to DRAW a line in the dirt , as often as not,you get too attached with a particular car and then your set for a ride.I call it the merry go round of used cars ,were you stop only you know.It would have been intersting to see how far the old girl couldve gone but thats like beating a horse to death almost ,i like the memories I have of her,so Im satisfied with that.
