But that list only includes one of the small Ferrari's, the
Dino. What about the 355 or 360? The Dino 308GT4? The 308GTB? The 512 Testarossa? The 512 BB? In addition, a good majority of the FR Ferrari's you mentioned were made well before the MR layout took hold on sports cars anyways.
Besides, if the car is mid-engined, your head (and thus, your ears) is closer to the engine.
Yes, it includes only one of the small Ferraris because it is the only one of the small Ferraris to be considered as desirable as a big front-engine V12 Ferrari.
And even then, the Dino is easily eclipsed by lesser V12 models such as Tipo 500 Superfasts, 410 Superamericas, and the 330GTC.
The "Dino" 308GT/4 is considered by Tifosi to be an aberration as it is the only road-going production Ferrari to wear a Bertone body. The 308GTB is looked at as the "poor man's Ferrari". Only Quattrovalvole models carry any significant weight, and even then you need a Vettroresina generation Quattrovalvole with carburetors for it to carry any provenance.
512BB? A good car, and the Le Mans/IMSA Group 5 variants have some clout, but they're bargain basement. Testarossas tend to make Tifosi vomit.
The 355 and the 360 are still too new to truly appreciate (or depreciate) in value, nor have they had significant enough impact on motorsports or in Ferrari's lineage to garner provenance of their own.
The list I created had three qualifiers: Collectible. Desirable. Classic. Not a one of the road-going Ferraris you listed, which (save for the 365GT/4 BB, 348tB, and the oft forgotten Mondial) comprise the entiriety of the mid-engine Ferrari fleet, meet all three of those requirements.
Perhaps, given another ten years, the 360 Modena will join this list, but it will be in a limited capacity considering the large numbers of Modenas produced and the fact that the Modena is carrying on in F430 form.
