    Rescued this FBI Suburban two years ago. Clay barred it, detailed and waxed. Wire wheeled all rust off from underneath. Added Powerstop slotted rotors and pads. Replaced Autoride shocks with Bilsteins. Added touchscreen radio with backup camera and ApplePlay. Everything works as should and no leaks.
