let us know what you are after as the body of knowledge on here is pretty good.
Note the F430 is really a development off the 360 (a pretty extensive one mind) but many of the underpinnings are common. One thing to bear in mind is the F430 was really the first V8 that could be massively different on MSRP as the options list was extensive. Depending on spec you can have a luxurious 'prestige' car with luggage for wafting around Europe for sauntering down to the local cars and coffee or a raw track / challenging road orientated ride. I see these two opposites like a 1litre sports bike vs, a 1litre supersports bike. Note this is without covering the Stradale / Scuderia options which are like the 360/430 RR versions.
It is for that reason that I see the F430 as the first time a used Ferrari price should not just be based on the age / miles & condition.
Not everyone sees it that way yet (especially dealers or owners who want top price for a basic car ;-) ) BUT it really is buyer beware because spec changes and mid-life updates can make a big difference in the car you get.
Ferrari did mid-life updates to both so make sure you understand what you are looking at and you can go into it with open eyes.
The best way to stay honest to yourself is mappings out your dream spec - understand its MSRP in period and then hold out until you get very close to what you want. If you compromise with lots of post purchase rationalisation you will likely only own the car for a short period or have the nagging feeling of "what I really wanted was...". This will only ratchet up when you go too a Ferrari gathering and start seeing options you had promised yourself.
Why not list your 'working spec' on here for both Tipo and solicit feedback on each option from owners?
That should give you a lot of good information:-
