First & foremost, any color wheel looks great w/ a silver car. Ehhh... maybe not black though.
Imho, it's hard to pull off 17's w/o a bodykit... or vice versa. If your planning or already have a bodykit you might want to put that into consideration.
Also, consider that the larger the wheel size, the higher the price. In the same token, the lighter the wheel (especially considering its size), the more expensive the wheel is due to manufacturing process ([cold-]forged/etc.). Those SSR Type C's posted above cost $300 each in 16" trim which are very lightweight. Volk Racing's TE-37 (really light!) can cost up to $500 each.

Just take your time, thumb through some more m'zines, check out wheel/tire sites (such as wheelmax/tirerack/groupbuycenter etc...)
Soon enough, you will come upon some nice wheels (& price) that YOU will decide to get.
Good luck!
