What do you reckon Rudiger? I reckon it's a US import (or a US Forces sale never exported back to the US?) cos of the amber side lamps - presumeably a NADA sold into Germany at the end of production (as some were) would have acquired clear side lamp lenses and possibly clear indicator lenses as well. Ad says it has a 3.9 and Weber as well as an upgraded cooling system. I'd say that improved it but others might prefer originality. Paint is a rather attractive metallic as well.
Overall I like it - evidence of careful significant expenditure is always a good sign.
