Difficult to know exactly what the car includes - based on the limited info. provided. The photos reveal a pretty straight body with added hood scoops, removal of Dodge emblem on the hood, decent paint, and overall a very presentable car. Mechanically, seller states the drivetrain is rebuilt - and the AD says it is V-8 equipped. Interior looks decent with an aftermarket steering wheel, seats from some other vehicle or aftermarket, and AC unit intact. So is it worth $18K ? If the car checked out and the body / paint are good, the price is in range.

Yup, may not be too silly a price if the car checks out.
I'd guess it has a 318, not that that's a bad thing.
I've never understood shaving door handles, except for lead sleds & such.

I'm also not a fan of the shaved handles. Takes away from a '71 Dart. Frustrating that people list a vintage car and leave out engine. That usually means 318. Like you wrote, not a bad engine but do sellers think we won't ask?

I agree. Car looks naked without the door handles - it's one of the first things that draws your eye.
