It's not really a concern, because I like some of the randomness in GT, I love when I discovered brands such as Saleen, Pagani, Cizeta, Lister, and much more, I know that we have a very nice line-up of hot hatches, but I was just using as an example, there are some types of cares that we don't have much representatives, like Hypecars, we only have really 2 or 3 as far as I can remembre (Veyron, Huayra, One-77) not counting the Enzo because is already a bit "old" if we compare to the recent cars, the Aventador is a "normal" production car (no limited numbers), and a bunch of other cars, that's why we ask for Koenigsegg and a modern Zonda (Cinque, Tricolore, ...). In the supercars there are numerous categories:
-"Baby" Supercars featuring 458, F430, Gallardo, SLS, MP4-12C,GT-R/GT-R Black Ed., Audi R8 (mostly the V10), Corvette C6/C7, Ford GT, V12 Vantage, Viper SRT10 Coupe, LFA, maybe more that I can't remembre now... (This category is very well filled)
-Baby Hardcore Supercars (track focused) - we have just a few, I just count 1, 430 Scuderia... missing the Gallardo Superleggera, SLS AMG Black Series, future 458 Speciale, R8 GT/new R8 V10 Plus, Corvette ZR1, LFA Nur. Pack.
-High Performance GT Cars - 599GTB, Aston Martin DB9/DBS/Virage/Vanquish/new Vanquish, Ferrari FF, Bentley Continental V8 GT/SuperSport, Jaguar XKR-S/XKR-S GT, Maserati GranTurismo S/MC Stradale.
-High-Range Supercars - Aventador, Murcielago (All of them except SV), F12 Berlinetta, SRT10 ACR/new SRT Viper, SLR.
-Limited Production Supercars/Early Hypercars - SLR 722, SLR Stirling Moss, 599 GTO, Enzo, Murcielago SV, Zondas (in general), MC12, One-77, Reventon, Sesto Elemento.
Not a wishlist, just mede this for some people to understand that there are multiple categories of supercars as you, car loves I presume, should know and to show how awesome this is, the variety is amazing if we think that "we have enough of this", I would love supercar races online with each person has a diferente car but still cars that are balanced, and do just like car magazines when reviewing some types of cars. This is why I love GT, I can feel each car better than any other game, I can compare and choose my favourite, which in GT5 was the awesome 458 Itália, and now with the new tire and suspension models it will be even more realistic, more feeling of the car.
