Well, to throw a wrench in the cogs of that... The 7 year maintenance with Ferrari is awesome; I agree. However, not every city has a Ferrari dealership and I believe he stated the nearest dealer is ~85 miles away. I'm not up to snuff on the Ferarri service intervals, but I'm guessing they are much smaller than an M3's and a 170mile round trip for service adds up.
That being said, if I honestly could afford a 458 Italia and not have to worry, I would get one in a heartbeat. When reality sets in, I know that the M3 is about as high of ownership as I will achieve and be comfortable. I don't make 250k+ and I don't have the disposable income to support the Ferrari lifestyle.
