Some experience with the 'other' exotic maintenance costs. Have two 12 cyl F cars (512TR and 512 Berlinetta Boxer 'i'). The routine stuff isn't too awful, but parts from the Fcar dealer can be horrendous, so some knowledge of crossover is very helpful. For instance, AC compressor from Ferrari is 1200, for identical one for BMW its 550. Fuel accumulator from Ferrari is 195, for identical one fitting a Volvo 850 its 75. Things like that.
The big fear factor for Fcars prior to the 360 series was the 5 year 'engine out' belt service. Pretty comprehensive, but the one last summer on my BBi was $13k. That should do me for a while. They found a hairline crack in a distributor cap - $450 for the cap - but were able to seal it. So you deal with that kind of stuff. Though I should be good with that car for some time. I don't want to dis the Fcars, because I'm clearly a fan, just giving a hint of the difference in maintenance since that was the OPs question.
I too live away from a Fcar dealer/service center, so loading it up for the trip is a bit of a hassle. The Ford GT just drives in the bay, half the dealership comes out to greet me... I mean IT... and they happily do what's needed. Had one service (short term owner) and couldn't have been more pleasantly surprised at the light service bill.
My car has 32k miles, and the history shows mostly 'normal' stuff except for a transmission oil leak and other niggly things. Pretty minimal though. In an Fcar, would've been far heavier on maintenance, that's for sure.
