I have been considering changing my 4200 for a Granturismo. I started looking at AutoTrader not sure whether to get a 4.2 or spend a bit more on a Granturismo Sport with the 4.7 engine. What I found peculiar was that the top speed for the 4.2 is given as 175 m.p.h. whilst the 4.7 is only 160 m.p.h. even though it has 40+ more horsepower. Is this correct?
