We were purely discussing appearance, not performance or handling modifications, I have and like both. As to what I buy, or what you buy, or what anyone else buys, and however they see fit to modify it, we can feel free to opine, but beyond that, I believe in showing respect to people and their individuality, and not to some arbitrary acceptability rules. You've expressed your opinion articulately, but you'll have to agree there's nothing factual there. It's arbitrary, it's how you like to see things, and it's not universally accepted.
Personally I think the true heart of the custom car scene is slowly dying because of the insane levels of conformity present in modern youth. I have more respect for the ridiculous custom ricer than for someone who's afraid to do something that doesn't get enough peer-approval or 'likes' on Facebook, or who lives according to some rigid rulebook about what's 'acceptable' or 'respectful' to the car manufacturer. If someone disagrees with the hivemind, bully them until they conform. It's a fundamental alteration of character and individuality, self-inflicted, and courtesy of social media, political correctness, and closed-minded liberal socialism. Bruce Jenner can identify as a woman, but we can't allow exterior lights on an American car?
How's about showing some respect for American ideals (and the spirit of the Mustang), primarily individuality and freedom? The appearance of one's car is artistic self-expression, and I enjoy a wide variety of that expression. Some I find ugly, some I find hilarious, some I think are amazing, but I appreciate everyone's unique individual expression and the effort and courage it takes to show it. You may not, and that's your prerogative, and it's not really an area where there are any grounds to morally lecture one another.
