My biggest complaint is that the Mustang is bigger and heavier than I'd like it to be. I really have nothing except ticky tacky minor issues like that. I think the stereo/interior/paint are good enough - those are probably the most common complaints I've seen on here but I don't share those opinions - at least not with respect to my car. I did share that the panel fitment isn't the greatest. The rear valence on my car just doesn't fit quite right due to incorrectly matching shapes.Any common complaints that need to be passed on?
