I personally think a clean, shaved car with nice paint is the best you can possibly do. Adding a lot of gawdy stickers and multicolored paint and everything is flat out ugly and in bad taste IMO. What looks better, a nice white t-shirt, some blue jeans, and some white shoes, or a bright red shirt with some yellow all over it, some white pants, and some brown boots. It's just a matter of style and taste, heck some people might sport that later outfit and think it looks great, but its just not my tastes. Thats just me though, do whatever YOU like and to hell with everyone else IMO. But like I said, me personally, leave that stuff to the real rally cars, they put that stuff on there because they HAVE to due to sponsorship and advertisement. You're car isn't a rally car, you aren't sponsored, basically I look at it like you're trying to make your car look like something it's not, and when has trying to imitate and replicate something every been a good thing.
BTW: Not sure about your town, but welcome to 90% of the country. Every since Fast & Furious everyone has taken their car, whether import or domestic, and added stickers and vinyl and everything on there.
