I bought a brand new 175cc Mercurio (18 hp) when I got my drivers license, age 17, in April 1964,. Was my 1st vehicle I owned in my name....cost $475.00 back then. Sold it when I went off to small college in Iowa in fall of 1965. Was a hot little bike for its size.....could out drag Sportsters and Single carb TR6 Triumphs up to about 60 mph when they would catch and pass.....it would top out around 85. Had a buddy that had a 200cc Metralla those days...it was about 2 more hp and would hit 90.......
