I need a opinion on a 73 plymouth duster value

Assuming clean title...For me, biggest question is ‘how much rust?’ Without knowing that, might as well use a dartboard - $1000-$6000
Also with miles that low, is the interior still good? That could be a big plus. Upholstery ain’t cheap and good original plastic parts are getting harder to find.
I agree on the value. Most people THINK because these old cars only register 99,999 before they roll over, that what ever is on the odometer is real mileage.
