The Holman Moody Honker, tested by Andretti, and he called it the worst race car he'd ever driven

Andretti praised Holman Moody for exceptional Nascar racers, and he should know...he won in Nascar too, but he said they didn't get it with sports cars. Again, he knows these things.

Here's something I found interesting about the Honker, it's chassis was designed by the same guy that designed the Ford GT, Len Bailey... Alan Mann Racing developed the chassis, but running the program and building the engines was up to Holman Moody
