I can't do 4k yet (Maybe after Xmas) and also been trying to earn credits to get the P1 to try out in Forza Horizon3 (soon) but you can make our own personalised Plates, so I thought of you and a Mclaren 570s 👍
I have no regrets buying it a few months ago and having 2 consoles running along side each other which I thought I might regret at first as I had a PS4 then PS3 for so long after X360. I tried XBone on launch (few probs) then got DriveClub PS4 never looked back until recently with there being no new releases about, I think I got my moneys worth so far just out of Forza6, FH2 & FH3 I am really enjoying all 3 photomodes, I just went for the cheaper Xbox one that came with Forza 6 bundle and it is so much improved since the launch version now. There are quite a few on here GTP who brought one after Drive Club and awaiting GTS..Not an easy decision, see if there are any offers or if you think it can work buying 2 consoles + Gold membership..but yes all Forza have the Mclarens in them.👍
p.s Don't forget you can get awesome things like this to throw around the Race Tracks
