There's no single answer to the price of a car in 1957. The price varied wildly depending on the make, model, features, and options. A basic, smaller car might have cost around
$1,500 to $2,500, while a larger, more luxurious model could easily reach
$3,000 or more.
To get a more precise answer, you'd need to specify the make and model of car you're interested in.
