I live about 200 miles from the nearest Ferrari shop and I still bought one. Some models, like the 360, are very DIY with a strong community. I've worked on lots of cars and I'd say that the Ferrari 360 is the easiest car I've ever had to work on. It's made to come apart and was originally put together by hand. Most fasteners are made of actual metal and there's very little plastic in the car. The car is literally made out of aluminum and as long as you don't drive it into the ocean, should remain corrosion free forever.
Of the group, I'd go with the Dino 308 GT4. I've seen a couple examples in person and they are very nice cars that sound great. Personally, I'd stay away from V12 models just because of the extra complexity and cost involved with keeping them running. Ferrari's aren't Porsches. They are tempermental low production race cars and can be very expensive to just keep running.
For the first time Ferrari buyer, you should know the following:
"Buy the absolute best Ferrari you can afford."
and
"The cheapest Ferrari is going to be the most expensive Ferrari."
