Many people feel the 360 is a much better looking car than the F430. They also feel the 360 CS is a more exciting ride than the Scuderia.
Regardless, the F430 will wipe the streets up with the 360; just as the 458 will clock any F430 variant with ease.
All three series are excellent cars and plenty were made, so the prices should continue to depreciate. These are all great cars to be enjoyed, IMO.
360 is probably the best "starter" Ferrari and there is virtually no premium for a MT version either. To me, the F430 was the first car to really be geared towards the F1 transmission, which explains why so few MT were produced - and those MT versions are now targeted by prospectors with high premiums.
The 458 is probably the last of the normally aspirated engine V8s (for a while at least).
