Ford has revived the 1964-1966 Mustang.
It's not as simple as walking into a dealership and ordering the classic Ford Mustang but you can buy a new body-shell of the first-generation model (the convertible too) and begin to 'restore' it yourself using Ford-approved classic parts.
Prices for the 1965 Ford Mustang body shell start at $15,000. The new shell uses modern steel and welding techniques that makes it actually stronger and more durable than the original.
Once you have the body shell you'll need the powertrain, suspension, brakes, electrical system and interior trim to build the car, which you can take from an existing first-generation Mustang or can purchase from suppliers.
The '64-'66 Ford Mustang is the most ubiquitous of all classic models. It is the most insured classic car by Hagerty Insurance, the U.S.'s largest insurer of collectable automobiles.
