Ferrari will not turn GT into a super car game. Gt hasnt been exactly an encyclopedia of cars either. GT has been a game about enthusiast cars, disregarding the price, power or speed. While most Ferraris have been considered super cars at their introduction, most older Ferrari's arent exactly speedsters today. In that S2000 vs Testarossa example, Id bet a stock S2000 could beat an early Testarossa around a fairly twisty circuit. Cars these days put their power down better and take corners alot faster than they used to. Its predictable that engineering (in any field) develops fairly quickly.
For example, an early NSX was a supercar in its day. But in GT4, its really just an average sports car. The Ferrari 348 wasnt really any faster than this early NSX. While the 355 was faster, its comparable to a modern NSX or esprit. Do you consider those two to be supercars? In GT4, the Merc 300SL is comparable in pace to a SEAT Cupra, the 300SL is a supercar. Any Ferrari built before the early 80s would get killed by a Skyline GTR, thats the majority. Sure, the Enzo, F50 and 599 GTB are super cars, but there really arent that many. Not enough to transform GT in the least.
So never mind that you want to see as many Ferraris as possible. What is your essential Ferrari list? What are the can't miss models?
Ill start with road cars.
Youll need atleast one of each generation of Dino V6/V8 cars. Simply, one of the 206, 246, 308/208, 328, 348, 355, 360 and 430. Simple. For now, lets ignore the 308 GT4 and Mondial Quattrovalvole 2+2s.
To continue MR Ferraris, theres the BB and Testarossa. Both enjoyed fairly long lives, so atleast a few variants of each would suffice. Lets go with the 512BB, 512BBi, Testarossa, 512TR and F512M.
FR ferraris is alot more complicated so lets just fish out some important ones, 250 GT Europa, 250 GT Boano, 250 GTO, 250 GTB, 250 GTB SWB, 250 GT Lusso, 275 GTB (My username is named after this car), 275 GTB SWB, 365 GTB/4, 550, 575M, 599 GTB, as well as the 400 Superamerica and 500 Superfast muscle cars and the 456 and 612 2+2s.
Last but not least are the "super cars", the 288 GTO, F40, F50 and Enzo.
That covers road cars. It should also be noted that there are racing versions of these road cars, most notably the F40, 360 and 550 among others.
Race cars, there are two types, prototypes and Formula racers. Since there are no signs of F1 cars being added to GT, ill talk about the prototypes.
Two of the most notable are the 250 LM and 275 LM. Both beautiful race cars. Theres the early Mondial and Testarossa. The 250 GTO race car is also well known. The famous 330 P3 and 330 P4 deserve inculsion as well. The 312 PB deserves inclusion as well, being the last of the old Ferrari race cars. I see you mention the 333 SP. I suppose it could be worthy, but its really not that special.
I realize I just named 43 cars, that more than 25, but I believe they are all essential. And its alot less than my normal wishlist of 100+ cars.
