Frankie,
Pretty good chapter about the blue RS ZL1 in my book- also includes Ken Barnhart's ZL1...good reading if I don't say so myself
Hell, the damn book is less than 4 crappy magazines if you buy it on Amazon.com
On the topic (and also in the book), might I cast a vote for the one and only 1968 Z/28 convertible built for Pete Estes - one-off car with factory cross ram, 4.56 gear, JL8 brakes, 'glass hood, etc. I've driven it and it is one wicked car - and nobody will EVER say they like "the other" Z/28 convertible more
