I used to have, actually my dad used to have a 1994 Dodge Viper RT/10 with the side exhaust

. It was a great sounding car and it was very quick. Against an ///M5 in acceleration i think the Viper would win by very little, but at top speed i most likely believe the ///M5 would win, what do you think?
P.S. Unfortunatley, we sold it two years ago.
