Nice Car

The Nice Car is a red shiny car that only appears in the episode "Sir Ed-a-Lot", and Eddy was washing the car and wearing sunglasses to make the kids think that Eddy has a shiny car. The car is an obvious allusion that adults were in the Cul-de-Sac at the same time Eddy was shining it. Eddy only hung around it primarily to look cool. The car is based on a mid-50's sports sedan, with the front end from an 80's Corvette.

Edd, Eddy, Kevin, Jonny, Plank, Nazz, and Rolf don't have a clue whose car it is. Ed, Sarah, and Jimmy's reactions were never shown.

The biggest mystery is whose car it is, although we can safely assume that, as none of the cul-de-sac kids are of driving age and because Eddy's brother is out of town, it belongs to one of the parents (probably not Nazz's, Edd's, Jonny's, Kevin's, Rolf's, or Eddy's, as they probably would have noticed).

It looks very similar to Eddy's Brother's car as seen in O-Ed Eleven. It is also the first car to be shown with an AKA license plate (AKA1).
