No I didn´t buy one.
Last year while visiting Hartford CT. on my way back to Sweden, I ran across the Tuxedo black COPO 9561 that Valenti Auto Sales in Wallingford CT. sold.
This year while standing in Geneva by the lake OH. talking to Mark Hassett, Jeff, and a couple they know, Jeff told me that the womans uncle once had a COPO 9561. She then told me that her uncle bought the car new at Jack Shaw Chevrolet, but it was stolen a year later and was never recovered.
While standing there this Le Mans blue Camaro passes us. I thought it looked like a COPO, and so it was ! The female owner bought this COPO 9561 in 1972, and she is determined to keep it.
