I owned 3 different model 3000s. I purchased one in Mexico City in the late 70's, and two in the early 1980 from a guy (Arturo Valencia ??) who was importing them into San Diego. Nice bike, Columbus SL and SP tubesets, and chrome forks. The frames were painted gold, and would start rusting in a year or so where sweat hit the bike. The older one had the BB cable guides on top of the BB, the newer ones had the new style under the BB guides. All were Hecho en Mexico....
