hi everyone, i need help!
i am curious that... if i got R1 & R3 GT5 disc. could i play with my (one) PS3 with either R1 or R3 disc? PS3 got no region lock right?
how about the DLC car? could i redeem all with different Region disc?
if so.. i prefer use my asia-PSN with R1 disc, could both Stealth and Chrome cars appear all in my garage?

thanks
