Me, I'll be able to finally breathe easier once we get the Pantera back. Any marque still not in the game yet (and not in Forza since the 360 gen) gets me nervous over what licensing issues might be getting in the way.
On another note, here's a fun/weird/mysterious turn of events I had today: last night I flipped a handful of cars that I originally won in the auction house, almost entirely because I had 50 million credits and figured I could hit the Autoshow and outright buy the expensive cars I'd previously picked up in AH. (The only reason for this is I get all itchy in the accomplishments-driven part of my brain when I look at the "original owner" field in the car's history and see something like xX=Wikkid__Marmot69420=Xx in the field instead of my own gamertag. It's sad, I know.) Unfortunately, one of the cars I put up for auction was the Nissan NISMO GT-R LM, which I'd forgotten was a wheelspin-only car. Of course it sold (for a little over 200K credits, which, eesh), so here I am kicking myself for having an incomplete garage again. I figure it's worth a shot spending the handful of Forzathon Points I have to buy four Super Wheelspins to try and get it back, but I come up empty in all four spins (well, OK, empty except for cash prizes). I'm still fuming as I decide to try and work off some annoyance by trying to nail a few of the remaining dirt drift zones I haven't three-starred yet. And after I finally get 100K on Tarn Hows in my monstrosity of an AWD-swapped S2-tuned '63 Beetle, I level up. And get a wheelspin. And use the wheelspin. AND WIN THE NISMO GT-R LM.
What.
