If you are a Chevy lover, or car lover in general this 6 min video is amazing. some things in his collection Every Chevrolet convertible since 1912 Wow! What do you suppose this collection is worth ? This collection belongs to Dennis Albaugh in Ankeny, Iowa , just north of Des Moines . The personal and private collection consists of 110 + Chevrolet convertibles... all years from 1912 to 1975 and Corvette convertibles from 1953 to 1975. That is a Chevy convertible from every year of manufacture EXCEPT 1939... The reason? - Chevy didn't make a convertible in '39 - and ended its convertible line in '75! His 'boy toys' include his own 18 hole golf course, copied somewhat after Augusta National. He is what you call a REAL Chevy guy, but his passion seems to be convertibles ! This billionaire made his fortune selling farm chemicals!
