1963 Ford Lotus Cortina Mk I

Dropping the 105bhp twin-cam into Ford’s lightweight Cortina bodyshell created a saloon car legend. Almost all came in white with the green side flashes, and their minimalist quarter bumpers became de riguer for several generations of Ford tuners. The first year’s production came with aluminium doors, bonnet and bootlid, along with an A-frame for the rear axle location. This is prone to cracking its mounts and was changed for leaf springs, but those earlier cars still command something like a 20% price premium.
