1970 Chevrolet Camaro Z-28
A 1970 Chevrolet Camaro Z28 in Astro Blue, built as a dedicated competition machine to contest the Anglo American Challenge series between 1997 and 2001, driven by its late owner Jim Graham. The car was among a batch shipped to Sebring for invitation racing and reportedly completed every event entered. Post-racing, it received substantial drivetrain and engine upgrades, including a high-specification 350ci unit producing around 440bhp. It made a final public appearance at Shelsley Classic Nostalgia in 2019 and is noted as a candidate for conversion to FIA specification.
