as what you had bought the model for originally as Bburagos are not really known to appreciate in value, mainly because of their "reputation" as a lower market sector/niche manufacturer, and frankly, the lower quality of most of their models, compared to middle market makers like AA and Kyosho. Only Bburagos that might have appreciating values might be a non0officially released prototype or some sort of special corporate gift model issued to certain people in very limited numbers with maybe a famous celebrity's/or racer's signature on it, but then the values for those are based more on the circumstances around the model and not the model itself......
