By the early 1960s there were very few “car crazy” teenagers in the world who hadn’t heard of Ed “Big Daddy Roth.” Roth was a larger than life character whose cars dazzled you by their wild lines, colors and chrome. He was as much an artist as a hot rodder.

Roth’s first hot rod was a 1933 Ford Coupe he painted in his parent’s driveway with his mother’s vacuum cleaner as a teenager. Going to high school in the late forties in California everybody had a hot rod and Roth wanted the best. “Big Daddy” went on to create such memorable rods and rolling sculptures as the Outlaw, Beatnik Bandit, Rotar, Tweedy Pie, Mysterion, Orbitron, Wishbone, Fang and the Druid Princess.

Although Roth loved typical rods he also liked the unusual in his personal everyday kind of cars. He fell in love with the new Kaiser Henry J, but soon removed the “hump” from the grille. After getting out of the air force he couldn’t keep-up with the payments and bought a 1948 Ford sedan. It was soon painted with signage advertising his painting skills in pin striping, flames, scalloping, etc. This rolling advertising became part of Roth’s way of life

owning various vehicles over the years.

Roth bought a new red 1970 Honda 600 Coupe which was quickly painted to promote Roth’s skills. The tiny Coupe performed yeoman duty over the next few years before being replaced by a series of Honda Civics. As well as being used for advertising the diminutive Honda hauled VW trike bodies and parts on a regular basis.

Time has taken its toll on the rocker panels which call for repairs, but this in no way will interfere with the original Roth signage. Inside the interior is complete and some areas require renewing.

The Honda’s 600cc engine runs well and little will be required except for some minor mechanical servicing to be out to cruise and show events again. A rarely seen microcar in its own right, this small slice of Americana will draw crowds wherever it goes.
