It us a while to find the dyno place. Very nice place, and the two dyno guys are nice as well.

Not bad, 458rwhp.
Your friends GT500 is the grey Kuwaiti one right? Seen it a couple of times here. One of the first '10 GT500's I've seen.

 

Yes it is

 

I could break dance on that AFR.

Don't see too many 575s make the dyno, but very impressed.

 

How is maintenance on these?

 

not certain on these but 550's are a breeze, probably the best and most painless way to get into a prancing horse.

 

I'd say maintaince is pretty good. Car doesnt much go to the dealer, even though the car is pushed pretty hard on the F1 track here.
We've had three ferrari's, F430 spider (Sold) California GT and the 575M. The oldest one is the 575, and not one problem. Im surprised with the brakes, they arent that great comparing it the CC brakes the other ferraris have, cars brake disks have never been changed and its been with us since 2004.
One of the best Ferrari's i've ever driver.
Power is just right, head to head with a stock C6 ZO6, only thing this lacks in is the "slow" F1 gearbox.

Btw, the clutch has never been changed, is that normal for a car thats over 6 years old? Our LP640's clutch was changed after 2 and half years of using it.
