An old car that once was upscale, but long since prime. Usually a smaller, ~20+ year old car, starting to rust; passed off as a car that could still compete with todays newer cars.
At some point we all had them:
Getting rusty at the edges, engine noise get louder every year, dents and dings, faded paint, about to graduate to hooptie status ect.,
Used car lots sell these to lower income people, mexicans, and destitute niggas at high finance charges.
She needs to get rid of that egg shell and get a real new car.
