Cadzzilla is a custom hot rod car built by custom car builder and legend Boyd Coddington and designed by Larry Ericson. This amazing and yet classic car is based on a 1948 Cadillac Series 62 Sedanette and was buit or built for rocker Billy Gibbons of ZZ Top. The name actually consists of 3 words: Cadillac, ZZ Top and Godzilla. Even the license plate says “I8TOKYO” ["I ate Tokyo" - a reference to famous Godzilla movie]. This hot rod is also know as “The Eliminator” in ZZ Top videos. This customization cost around $900K at the time.

Billy Gibbons is a fan and avid collector of custom cars and motorcycles. His custom vehicles were a mainstay of the earlier ZZ Top videos and were also used for promotion.

CadZZilla wasn't featured as prominently in ZZ Top's videos as "The Eliminator", but it appeared in "My Head's in Mississippi" and in "Burger Man" — pulling out of the parking lot of a diner at the very beginning of the video. When CadZZilla has left the frame, it reveals a brief view of 'The Eliminator' parked beside the diner. An artist's rendition of CadZZilla was used on the cover of the Recycler album. In the video for "Doubleback", which uses Back to the Future Part III footage, CadZZilla appears at the final showdown and similarly to the early Eliminator videos, three sexy women get out of the car and solve the problem.

The car was well-received in the custom scene. Gray Baskerville, Senior Editor of the Hot Rod magazine, even named it as one of his favorite custom cars ever, and called it the epitome of the "Dare to Be Different" era.[14] The intense customization cost around USD 900,000 at the time. CadZZilla was shown outside the United States, for example 2005 at the 14th Annual Yokohama HOT ROD Custom Show. CadZZilla's timeless looks motivated and inspired Richard Ferlazzo to design the Holden Efijy showcar.

Scale models in 1/24 and 1/64 were produced under license.

Other cars and motorcycles

• HogZZilla. To accompany his CadZZilla, Gibbons decided to customize Harley Davidson motorcycles with matching trim. The name is a conflation of the Harley Davidson nickname HOG, ZZ Top, and Godzilla.
  
• Kopperhed. Based on a 1950s Ford sedan: radical remodeling of the roof creates the look of a three-window coupé.
  
• Mambo Coupé Based on a 1936 Ford Coupé.
• Slampala. Based on a 1962 Chevrolet Impala. The modern air-ride suspension allows the car to be set to extremely low ground clearance—a classic "lowrider". The slang term for this is "slammed", hence the name Slampala, a conflation of Slammed Impala.
