Aston Martin introduced the Mark III in 1957, an evolution of the DB2/4 that ran from 1953 until 1957. The Mark III carried the grille shape that would go on to define Aston Martin styling and came in an innovative 2+2, three-door hatchback arrangement — years before it became a small-car standard. Under the bonnet is a 2.9-liter inline-six derived from a Bentley design and updated by Tadek Marek. The car was a serious grand tourer in its day, making up to 178 horsepower with an optional dual-exhaust system and accelerating from 0-60 MPH in 9.3 seconds. The handling and comfort were also praised, although the $7,000-plus price tag had its detractors. This Mark III coupe is immaculate inside and out, and an important model in the companies history, bearing design elements that can be traced to the Aston Martins of today.
