Couple of observations:
The Honda GB500 in the Wednesday lot marked sold is supposed to be "all original". The exhaust is not. As is clearly visible when you compare it to the three GB500s in the Thursday lot.
The 1982 CBX in the Thursday lot was up for auction by Mid-America in a previous year either 2017 or 2016
Same for the red 1979 CBX with VIN 19552 in the Friday lot.
Both Kawasaki Triple 750s in the Thursday lot have a terrible decal application. No idea who paints these things so awfully
The 1980 Black CBX was for sale on ebay before. Last in September of 2017 in NV. Sold for 10K Mileage still the same
Check out the two Rickmans in the Friday lot. We may have seen one of the bikes before.
The extreme low mileage (4.7) 1981 CBX, Friday lot, has no saddlebags and no rear turn signals. A tell-tale feature of a "school bike", not a collector's bike
The black 1979 CBX , Friday lot, is, of course, NOT original. It is a repaint and has the wrong rear shocks, among other things
The red 1979 CBX in the Saturday lot is a low VIN but NOT early 1979 production. This VIN puts it into April 1978 production
