If the money isn't an issue, then why not?
You only go around once, and you can't take it with you.
If I had an extra $10k doing nothing, I'd trade my black '13 on a the matte gunmetal black/r '15 with cruise , ABS, and the angrier black pipes.
And, BTW, in reading the specs for the '15 in Canada, I read this:
"Motorized headlight aiming system is operated by a dial switch and provides 2.5 degrees of adjustment from level."
Does the US version also get this for '15?
