Funny enough, the history of bootleggers and moonshiners also blends into the history of NASCAR. The American Historical Vehicle Association has put together a short article on the subject that basically says during the 1930s and 40s the Ford V8 coupe was preferred for it's speed.

Cars or trucks? Succesful bootleggers were selling in bulk, so Model T (and later Model A) trucks were popular. The REO Speed Wagon was also very popular, it had a bigger engine than the Fords and could run faster. Some 20's cars known as legendary bootlegger cars are the Hudson Super-Six and the Studebaker 6, a model so popular with bootleggers it was nicknamed the "Whiskey 6".

Stutz was the number one sports car and racing company in the 20's, sort of equivalent to Ferrarri today in that respect but more approachable pricewise. The Stutz V8 was a bootlegger model fast enough to evade the police or the klan (the popular KKK of the 20's ran morality crusades and sometimes targeted bootleggers). Buicks and Lincolns were also popular with more well heeled bootleggers, these were both semi-luxury models but quite fast.
