Christ, some of the things listed in here aren't that bad.
Bonnet bra's serve a purpose on the right car, having one on a rat-look euro styled saxo or along those lines, is when it's too far.
I have a wee list of things I hate too.
Shopping Lists
Sticker-bombing
Any aftermarket wheel besides Speedline, Rota and Team Dynamics.
Open Cone Filters
Any exhaust bigger than 3.5inch
Any non OEM lights
RIPSPEED/HALFORDS parts
Any kind of bumper/skirt/vent/spoiler which gives no downforce, no air to anything, or if It's on a stupidly crap car.
I think a website any Chav hater has to visit is:
