Buying from afar
I think the faults are very trivial at this price point. I can honestly say I have never used the heater in any of my cars. If there are any undercar pics, look for the speedo/odo cable. Maybe need a new cable? Maybe it's not engaged at the speedo gage. You'll need to get the headlight doors squared away. There aren't many of these cars left that haven't been monkeyed with at some point. Unless there's something lurking we aren't aware of yet, I would say that's a good Charger buy at that price.
