I can't speak for the other two "strange cars", so I guess I'll get things started with my "strange car"...
Its a 69 L48 (300hp SB) with the Special Paint option. It is one of only a handful of 69's painted GM's paint code 80, Powder Blue. Even though the pic shows the car with "Hockey Stripes", it is also believed to be a Stripe Delete car as well.
In addition, it is a highly optioned car; Rally Sport, Super Sport, Am/Fm "Blue Light" stereo, Electric Clock, Speed Warning Device, Light Monitoring System (aka Vigilites), Air Conditioning, Tilt Steering Column, Power Windows, Power Steering, Power Brakes, Remote Control Mirror, Vanity Mirror, Courtesy Lights, Space Saver Spare, All Original Tinted Glass, Deluxe Seat Belts, Door Edge Guards, Vinyl Roof, Center Console, & D80 Spoiler.
