Hahahahahah
You guys or are "racing only" lovers or I don't know what you are. Car lovers isn't.
The magic of Gran Turismo is to be "The real DRIVING simulator". Driving the most cars you can, getting to know them, read about them in the descriptions, know different cars that you didn't knew before. Have fun racing a slow kei car or a supercar. It's all in the package.
I drove, customized, loved, tried, driven again and again and again each one of my almost 1100 cars. 300 premiums, 800 standards. And I love every single one of them.
GT5 wouldn't be the same without the BMW M3 CSL for example. I wish it was premium, I agree, but it's not... I enjoy the standard. Without it, I'll miss it.
You guys are looking and acting weird. You don't look like Gran Turismo players.
If you play GT since the beginning, it's impossible to not understand how "oh, you really drove +100 cars in GT5".
