Holey moley! I can't believe we're seeing hi-res shots this up-close so soon
As far as the trailer hitch goes, it might need to tote around some testing equipment. On another forum I frequent, we have a few members from Australia who've indicated that trailer hitches on their passenger cars are more common than here (one of them had a Holden Commodore SS with a trailer hitch) so it could be a hold over from that, since the cars were engineered there.
I hope though that those taillamps are placeholders like the headlamps are. I love love LOVED the taillamps on the concept with the round brake light/signal light set inside the lens. I hope the production model gets the concept-style taillamps.
