both are stock the 740 is an auto who would win?

 

I'd have to give the nod to the 740....those cars are fast, even with the large size they can do mid 14s in the quarter. I raced a 704i (I know the iL is bigger) in my dads GS430, and was barely pulling on him until we really got going, and a stock max would get killed by a GS.
