Great Looking Car!!! This is a special edition GT500 Mustang made by Shelby. Here 'KR' stands for King of the Road, not Knight Rider. It commemorates 40 years since Shelby had another 'KR' series. With a Ford Racing Power Upgrade Pack (revised ignition timing and throttle calibration, plus a cold-air intake) this car now has 540hp. It also has a different exhaust, short-shifter and shorter final drive ratio (3.73:1 rear end versus stock 3.31:1) and Ford Racing suspension. The carbon-fiber hood with the hood pins and new twin scoops is also different. Ford is building 1000 examples, so they may even appreciate. If you collect Mustangs, this would be a worthwhile addition to your stable.
