Why it matters

The M-Code was the Tri-Power 390 option on the Thunderbird Sports Roadster. Ford built only 37 in 1963, which makes it the rarest of the two-seat style Thunderbirds.

How rare is it?

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Lee Iacocca had designer Bud Kaufman create a removable fibreglass tonneau for the Thunderbird convertible, which hid the rear seat and gave the car a roadster look. It became a Sports Roadster package for 1962 with wire wheels. Sports Roadster production was 1,427 in 1962 and 455 in 1963, and only 37 of the 1963 cars were M-Codes. eBay's blog says 119 M-Code roadsters were built in 1962 and 1963 together.

Identification guide

How to tell an original from a replica or later conversion.

M-Code cars carry an M in the VIN. The engine is the 390 cubic inch V8 with three Holley two-barrel carburettors, rated at about 340 hp. Sports Roadsters have the fibreglass tonneau with headrests, Kelsey-Hayes wire wheels, a passenger grab bar and no rear fender skirts. The original build sheet is the usual proof of a genuine car.
