I just had the 30K mile service done and it came to $2000 including a heat shield and a couple other little items that needed replacing.
They also performed over $3K in warranty work that was billed to the factory.
FYI, the 32K service included the following on my car:
flush, replace every fluid in car (engine, trans, brakes, etc)
replace all filters (fuel, oil, air, pollen, etc)
new engine acc belt
torque a bunch of things
Warrenty work included:
door moldings torn (windows were maladjusted)
fuel injection rails
new motronic ecu
new air flow meter
some other things
My dealer (Auto Gallery in LA) is not particularly speedy (3 weeks to do what is only a couple days of work) but they pay attention to every little thing and the car runs a lot smoother now. I thought for the amount of work they did and the fact that the car is an exotic, the price was only a little horrible. I figure this much work on my Chevy would have been about $900 (tuneup, fluids, etc).
The funniest thing I found is that they said I was the first 30K mile service they had done since none of their other customers drive the car as much as I do.
Servicing the Maserati is a little bit of sticker shock but in 30K miles over 22 months, the car has been relaible and fun.
