Classic examples- VW Rabbit convertible, Mazda Miata, new VW Beetle.
Also Toyota Rav4 and any hybrid such as the Prius.
The sitcom 'Yes, Dear' did an episode in which the main character bought a white Mazda Miata and become frustrated when the car was constantly labeled a 'chick car'.
Chick cars always have automatic transmissions.
The only 'chick muscle car' was the baby blue colored 'Ladybird' version of the Trans Am.
Several characteristics of a chick car include:
-weak engine (usually 4 cylinder, less than 3.0 liters, less than 180 horsepower)
-sometimes convertibles, but once again, it really depends on how the car operates
Person 2: Dude that's a chick car
Person 1: How? It's a convertible like your Corvette
Person: Except my Corvette can push 190 and your car can barely get 90 because it has a shitty engine
