The Turbo isn't my track machine. The Scuderia is.
In any case, I do think that the GTR is a spectacular car for what it is but that's the thing, when I drove it, I almost felt like the car was the superhero because it just felt so capable. I feel the same way whenever I drive my Turbo. Almost seems like it's idiotproof. I'm just trying to illustrate that your skills become more important when you're driving a car such as the GT3RS or the Scuderia that was designed with the track in mind. That's all.
Everyone has a different goal when it comes to finding the right car for them. I'm not contesting that by any means. You'll get a different opinion from everyone here, guaranteed. The bottom line is, only the person buying the car can decide what suits him/her best.
