That Custom Vehicle comment is a cock-up by whoever does the Facebook page, I can absolutely confirm that the game doesn't support that feature, you'll be seeing that vanish shortly. I'll let AAUK double confirm this.
Beleive me, it would be a cool feature, but it'd take us another two years to add it!
There we go, that makes sense. Called it on that one.
It never ceases to amaze me how blatantly wrong a marketing team can be when presenting information through this sort of outlet. What DOES amaze me is how indifferent or incapable those teams usually are. Facebook pages are the kind of thing entertainment companies pass off to an intern-level hire in my experience, so that could be SOME sort of explanation (for their sake, I hope so)... but it doesn't make their misinformation any less of a tease to all the folks who got excited over the idea and will buy the game thinking it has that feature. Now everyone who follows that facebook page will be disappointed on SOME level about that non-existent feature's absence.
That's just cruel.
...Anyway, thanks for always clearing up these dangling concerns/questions for us, S0L. We appreciate you dropping some knowledge on us.
Looking forward to an impending Nintendo features reveal! HERE'S HOPING FOR AN EXCLUSIVE CHARACTER. (I'm aiming at the 360 version, myself, I just think that'd be fair and cool.)
