Some examples of cars considered flops in different eras include:
* Ford Edsel (1957-1960): Often cited as *the* quintessential automotive flop. High expectations and poor design led to disastrous sales.
* Pontiac Aztek (2001-2005): Criticized for its unusual styling and ultimately unsuccessful attempt to blend SUV and minivan features.
* Toyota Prius (1997-Present): Although a massive success overall, the first-generation Prius was considered a flop by many at launch for its styling and limited appeal.
