If you pay the money for your car, whatever it may be, do what you want to it. Its no one else's business what you do. BUT, just know that whatever you do, there are going to be people that both love it, and hate it. So don't take it personal when someone else's opinion differs from yours. Now myself, I really hate it when people do things like body kits, big rims, hood scoops, things of that nature. I'm deff a stock person, from an EXTERIOR stand point. Now things like engine work and horespower increase, I'm all for it. I just like my car to still look like what it is, a Mustang, not an import. I have an 05 V6 convertible and I love it. People keep saying "You have a V6 because you can't afford a V8". And they are absolutly right. I planned on getting a V8 but instead of costing 31k like I thought, the dealer wanted 41k, no thanks. I see nothing wrong with owning a V6. But I also don't see anything wrong with doing mods to one either. Hey, if thats your thing, go for it. I just personally don't care for it. Some of us don't have the money lying around to get a GT. Myself, I plan on saving money and getting the 05 GT within the next year or two. I just couldn't get it this year because they wanted to much for it. Plus, I'm only 21, so this girls insurance would be pretty high 
So, just to put my two cents in, I really don't like cars all "hooked up" on the outside, especially Mustangs, they should keep their muscle car apperance. But if your into that, more power to ya
