PRODIGY3000

The 1991 Mitsubishi 3000GT Twin Turbo was one of the first mass production cars to have a standard Active-Aero system which had retractable front and rear spoilers that popped up either automatically at 45mph or with the button on the console. They were discontinued after the 1996 model year. Had one back in the late 90's. Love these damn cars.

They're finicky systems because of how exposed they are but they're cool as hell.
