Than what? A 4.2 maybe but nothing in it between a GTS 4.7 MCS.
Believe me, at Le Mans I'd say out of all the cars there, 32, 42, GS, GT there is about 5% differential if that in all the cars performance.
Having owned a 3200, 4200 and GTS and having driven a GT a fair bit before I ordered the GTS, I agree with this. Anyway on the road a car needs to have a major power to weight difference -say 20% - for it to make any meaningful impact. All great cars and.....all slow compared to what you can get out the box with things like the M3/M4 now. You don't buy a Maserati to have the fastest car for the money.
