Desperately need rims on stock

Well I was more looking at jeep aluminum rims and mustang rims. I was looking for something more around 16+ inches for my personal look of choice. Also I've found 18 inch custom rims but I'm not sure of they will fit they have a 10 inch width on the ad off of a dodge caliber. My rims are fine I just don't like the cop car steel look personally.
