Vintage Cars: 210 chevy, numerical designation, 57 chevy

Question
what is a 57 chevy 210?

Answer
The Chevrolet Two-Ten, or 210 was the midrange model of the Chevrolet car from 1953-1957. It took its name by shortening the production series number (2100) by one digit in order to capitalize on 50's numerical auto name trend. The numerical designation '"210"' was also sporadically used in company literature. It replaced the Styleline DeLuxe model available in previous years. This model was dropped following the 1957 model year to be replaced by the Bel Air.
