My suggestions are as follows...
Conservative looking but nice:
16x7 Mille Miglia Cello (silver)
Less conservative in terms of size:
17x7.5 Mille Miglia Cello (silver)
17x7.0 Moda R3 (silver)
Less conservative, racier, but pricey:
17x7.0 OZ Racing Superleggera (gunmetal)
I would recommend a silver wheel on your car. If you do
not have a strong and overwhelming desire to get white
or black wheels (which you don't seem to) I suspect that
you may come to regret them later. A bright silver painted
wheel is always classy and classic, I doubt you would feel
they were the wrong choice in a year.
Unless you've modified your suspension, or plan to, stick
with the 16x7 Mille Miglia Cello I say. They will offer a nice
wide profile for some decent rubber, you won't have to be
so attentive to your tire pressures with minor temperature
fluctuation (easily the biggest chore with low-profile rubber
other than trying not to curb your new wheels), and you're
not going to have to put up with 4x4 fender gap.
You may also want to look at the ATS "DTM" and "DTM2000"
wheels available from Discount Tire Direct. The wheels that
I listed above are available from Tire Rack.
Cheers, and good luck...
