A 1960 Ford Falcon has a terminal velocity of 1024.056mph. It would have to begin it's dive from 6.6 miles and maintain a path normal to the ground. If it doesn't the terminal velocity is 75.5mph. With the car vertical it would take 1626ft to reach 220mph. It takes the Peregrine Falcon about 1000ft to reach 220mph and it has a terminal velocity of 250mph(I didn't do the calculations for the bird).
