Wow, that's something. Shame it's an 83. Having owned a few earlier ones they need to be kept out of the weather if they are to remain as new for 40+ years. Plus the old 3 speed Auto's never did the 4 cylinder justice and need swapping for a later auto or manual.
If it was an 87+ with those KLMS it'd be worth up to double that + to the right buyer IMO.
