What about this 71 Dart?? Advice?

Hey guys, I don't want to break any rules, but looking for honest opinions on this 71 dart.
I have a 66 dart sedan slant, that I have fixed up to be a driver. This was the first mopar old car I have ever had. I bought it 2 years ago. Intention was to have a car for my son to drive, but I just don't feel safe for him, 9in drums, steering, seats without head rest, crappy seatbelts etc...
Anyhow in the market for a slightly less old Dart, with 2 doors, and disc brakes.
Found this add on CL 1971 Dodge Dart
but has been on there for awhile which means either too much money, or ??
This is what I see, tell me what else is going on.
1971 Swinger, with slant, with dual exhaust?, a 4bbl carb?(why), heater hoses that are MIA, old tires, interior mess.
Anything else pop out? And price-wise isn't this sorta expensive for a car that will need major interior work? I am trying to ignore paint job, which appears to look really nice. I have yet to see the car in person. ok now tear into it.
