Impact was inspired by Ron Whiteside's 1934 3-window.[1] Whiteside began building his '34 in 1986. He showed pictures to Boyd Coddington, asking Coddington to finish it, hoping to have a Ridler Award-winning project.[2] Chip Foose, who worked for Coddington at the time, also saw the pictures, and conceived a sister car, a '34 roadster, for Betty DiVosta, whose husband Buz owned two other Coddington creations.[3]
Then, as a result of the failure of Boyds Wheels, Coddington's rod shop closed. The unfinished roadster was sold at auction to Berg, who completed it as Impact.[1]
Impact was entered in the 2001 Oakland Roadster Show. It won that year's America's Most Beautiful Roadster award.[1][4]
