Volk RE30 in 18"

[zippin]

I have an 09' touring, non sport model with stock 18"s. I came across a really strong deal for new Volk's RE30 in 18" setup. Should i do it just to improve the looks? Or if upgrading bug is upon me, is it smarter to bump up to 19s and get the whole kit, e.g. wheels, tires and spacers? If the later, I will hold off until my oem tires are done....which will take a while at my pace of 200 miles p/month. The deal on the 18s is really good, so that is the only reason i'm entertaining the idea of just replacing the wheels. Give me your 2 cents.
