Got the Dinan Stage 2
Oh my goodness! What an incredible boost in power. I own the highway! I swear 50-100 happens in about 3 seconds. 0-60 is like blinking an eye. Top speed yesterday on a race-track straight-away 150 mph and the car was just cruising as if it were on a cloud. If you own an M3 and need a family vacation sedan, the GT 550i with the Dinan Stage 2 upgrade is a must! People give up following me when I pass on the highway!
