Emerson Moser , 46, of Cincinnati, general counsel for Meridian Bioscience, on his 2010 Dodge Viper ACR, as told to A.J. My dad was a General Motors engineer, and we spent a lot of time going to racetracks and car shows. When I was in college at Purdue in the 1990s, I was walking across campus one day when I saw a Dodge Viper on display in the Engineering Mall. I thought: This is the coolest, most exotic American car I have ever seen. It had a V-10 engine partially developed by Lamborghini.
