Never got to meet Zora, but did meet Elfi, and in fact had a card from her after Zora's passing.... We have met the two Daves a few times. Dave M is very charismatic of course, and very interested in everyone's Corvette. We had a long chat with him when he signed a large format photo of our '78 at Bowling Green (couldn't take the car for hime to sign!) as he was fascinated in the license plates of the UK. (The 78 model was the first model year that he had been "Chief" for in its entirety) We met Dave H in the US and over here at Le Mans a few times. In his early days a Cheif Engineer, people were a little dissapointed in his "quiet" style, especially after Dave McLellan, but we found him charming and a real car guy. I recall we saw him in what we think was his own Vette at Pacific Grove during Monterey Week, just "hanging out" with other car guys with all sorts f different cars.
