I rarely would ever recommend this show but LAST Wednesdays episode was one of their most informative. Its on Ondemand. Anyways they visited this collector of 3 wheel vehicles. Would be a typical snorefest but these had a very interesting history I had no clue existed. The vehicles were called invalid vehicles made in England that were given to injured soldiers after WWI. Many had motorcycle engines and the government kept them up for the soldiers. One was powered by using hands for locomotion. The collector who was selling some of these told Mike soomething very valuable "just because its rare does not mean its valuable". Of course Mike gave double what the collector wanted, yeah what a fantasy a dealer paying more.
