I bought the beta as well, it is just everything you can ask for a car like this. When the tyres are cold, this car won't give you anything, but is everything on temperature then you can do everything with it. You can just trust this car blindfolded even with the standard setup.
If you like open wheelers, and like classic F1, get this car. Just worth any bit of it. And is it just me, or did old f1 cars just that damn good, compare to the last 9 years.. -.-
