As long as it's a proper RUF race car and does'nt have the Prsche name or logo on it there should'nt be much of a problem. It would be fantastic if they got one in.
Thats a good idea, loads of people want Porsche race cars in GT4 so if PD can't get any make an RUF with the same performance as a racing Porsche but with the RUF badge and a fictional paint job.
actually the first one is an RTurbo. This is the RGT. the RTurbo is......turbo, and the RGT is the Ruf GT3. Naturally aspirated. Both cool, but the RGT is Race car gon road car (ala GT3) and the RTurbo is high horse power road car.
But anyway.......IF IT'S A PORSHCE, IT WILL ALWAYS BE GOOD ENOUGH FOR GT4. It doesn't even matter which type it is or if it's a RUF, a STOLA or a GEMBALLA!!!
