I was in your shoes about 2 years ago. One of my questions was, "when does the honeymoon phase go away?:" or something like that. Well, everyone who responded agreed that it never does fade. I am proof that they are correct. My serous search started in October 2012 and i brought her home June 2013. It was one of, if not the most exciting part of my life thus far. So i'll bite and answer your questions as best i can.
-prices seem to have dropped somewhat for the 2005 and 2006 models (mines 2006).
-i think they are asking around 120 to 135 for decent ones. 2008's and up have not come down much as they are still in the 150's to 160's (same as when i was looking)
-clutch change is usually the most expensive maintenance item at around $5K to $7.5K. i would probably opt for a car that will not need this anytime soon. i'm hoping to get at least 5 driving seasons in mine b4 i look to get this done in my car.
-inspection locale? well, i think many of us on here can give you a recommendation within 24 hours once you find out where your dream car is located. I used Fast Cars in Redondo beach, CA for the F430 and i used Miller Motocars in CT for when i was contemplating a 360.
-F1 vs 6 sp? don't know if this is what u were asking about but i originally wanted 6 sp until i drove the F1. It was the only F1 i drove and i bought her. It's that great! shifts lightning fast and is waaaaaaayyyyy more fun! not only that, my wife can drive her with ease. she likes to tell her sisters that she can drive the Ferrari. i think some women get intimidated by the Ferrari. Well, i was at first too though. probably because i never drove anything with that much horsepower or have that high of a price tag.
you are welcome to PM me or email. glad to help. work has been really busy so don't take offense if i don't get back to you for a couple of days.
