Holy shit! You must either be single or have a sugar momma! .
Currently the former, but not averse to entertaining offers from the latter.
Probably obvious to you, but the 575M and F430 are not usually everyday drivers. Hope you have something else to drive. Ordinary daily driving will quickly devalue an investment in those types of vehicles. They aren't Caymans. Good luck all the same. I will be eagerly awaiting your return to learn how you chose. In fact, keep us informed of your search and thought processes while there.
Blah. The 575M and the F430 are two of the most "reliable" Ferraris made as of late. Yes, I'm aware that's a very relative term though. Buying "modern" cars that aren't necessarily limited run is also one of the worst investments imaginable. Depreciation (i.e. miles) is barely in my scan. I don't even really "daily drive" my Cayman now. I've put 23k miles on it in 3 years, but it's been driven from TX to CA twice. Granted, I was deployed twice during that time, so ya.
People who buy nice cars to not drive should have their keys taken away. If you gave me that $24 million Ferrari from Pebble Beach, I'd drive the shit out of it. Unrestored 427 S/C Cobra? Who's up for a road trip? Sorry, cars are meant to be driven.
