CSX 2129 is the second of two rack-and-pinion 'Sebring'-specification Shelby Cobra 289 Works chassis built in early 1963, making it among the most historically significant surviving Cobras. Campaigned by Ken Miles and Bob Bondurant during the 1963 USRRC season, it contributed to Shelby American's manufacturer and driver championship victories that year. Following a distinguished racing career, the car was comprehensively restored to its original Ken Miles #98 Works livery and has since earned recognition at prestigious international concours events.
