I was at the Pleasanton, CA Good-Guys meet yesterday. One of the cars on display was a 68 Z28 convertible that was delivered in Colorado. The paperwork on the car looked original and very extensive. It indicated that the car also had the JL-8 service option and the cross-ram in the trunk. Numbers were matching. The car was blue with blue custom interior with fold down rear seat.Is it possible that this is a real Z28 convertible?
