Would these mods look ugly on a 2005-2009 mustang?

lambo doors are ugly on anything and to me they jjust scream "look at these cause my car's not worth looking at by itself"

Short answer: Yes

Long answer: Yes because I personally believe mustangs are beautiful the way they are, no mods needed. It's like putting make-up on a beautiful girl; overkill. But do what you want man.

If you're doing this to impress the ladies: I'm a chick. It's not impressive it makes you seem like you try too hard. Stick with the classics mannn.

Apart from the Saleen body kit, they all would look ugly especially the Lambo style doors, the only car I've seen that looks good with those doors are Lambo's funnily enough:)

Yes and no. If you go to car shows then yes. If you use it for a daily driver then no. It is a custom Mustang, It is your Mustang. Your call.

Get it blown have it sticking out of your bonnet
