Well, I have a 1992 940 non-turbo, ok it's not from the golden years of 1993-95, but here's a list of the problems this car has had at 164,000 miles:
Blown head gasket (knew that when purchased),
Leaking rear main/oil pan gasket,
leaking coolant into transmission fluid- needs new radiator (maybe new tranny later- yeah!),
frozen caliper slider pins,
ABS light on- bad sensor,
Driver's side power window rattling,
broken e-brake cable

The only saving grace is there appears to be an unlimited supply of these cars in the junkyards. My last count at my smallish junkyard (probably 500 cars) was ten 740/940 sedans.

Good luck!
