Understanding that there is a good mix of personal choice in here, I'd be interested in hearing people's opinions on the 15 inch wheel/tire set-up versus the 17's. 
I love the the authenticity with the 15 inch set-up.  The polished 17's look at little too 'new' for me, but I have seen the 17's with the matte gray (graphite) centers and polished lip/spinners that look fantastic. 
Whatchya think....?  Thanks,
