Here is my brother-in-laws.
Australian 1980 Mitsu Colt Bored and Balanced 4G12, King Springs, Koni Shocks.
Stephen and I stripped this back to bare metal and resprayed in Jag metallic blue. It's got a customised rear bar (the number plate cut out), rims from a Toyota Liteace (don't know what they're called in the US), with the centres machined out. This had the power economy shift (or eight speed if you like), that's 2 diff ratios, it's like overdrive in every gear if you choose. They should have done this in more cars, but I don't think people understood how to use it, so they went back to a standard 5 speed in the later models. Australia never got the 2 door.
