For sale/trade 1963 Dodge Dart GT

it's your car-- you are advertising-- you need to put a price on it & potential buyers will respond.
ad states tranny doesn't work-- & won't start at ignition--- that makes the car at best a project/parts car-- those are potentially big items to fix.
If you where local I might offer $500 with those problems-- Interior & rust would have to be inspected further.
Good luck with the sale/trade, Lawrence
