New 2012 Prius C owner

After a little over 3 weeks of driving the car I am very pleased with it. I bought it to save on gas traveling to work. I travel 75 miles each way and had a Hyundai Accent. It was a very basic car but got 35 mpg, which is good for where I travel. The Prius has averaged over 55 mpg every tank so far ( 3200 miles ). Oh, the car is a 2012 C3. I am intrested in a few mods,. nothing big. I will probably paint the grill, and part of back bumper, and have already tried blocking the grill since it is still getting in high 30s at night here.
I have a set of 15' Scion alluminum wheels and a set of 16' wheels off a VW that will fit the car. I will send photos of them of car when I try them.
