Honestly I'm probally the most anal retentive person you'll ever meet when it comes to getting my body work to look good. Fender/hood gaps are a huge "idiot beacon" especially when their so easy to fix. I'm normally the one that'll tell them "it's just a few bolts riceboy, fix it." If it's at a show or strip I'll even offer to help. The things that I hate to see thought is when the parts aren't even for the car, and there's no attempt made to correct it. The thing I hate about those M3 looking fenders is this:
The fender doesnt' follow the lines of the "A" piller. If you want the look then get some junk fenders or take yours off and put the Louvers and chicken wire in them.
Don't get me wrong there are some good ones on that site too, I'm not totally Anti-rice, I'm just anti-shoddiness. I know a guy who owns one of the local shops that does most of the body work for the local Rice crowd. He's got a solid black Del-sol, that looks almost stock other than rims and tinted windows, he's layed 10 coats of CC over the metalic black basecoat. looks like a mirror and you could just about fall into the paint it looks so deep. Under the hood he's running a twin turbo Vtec, All Go and No Show, the man has my utmost respect.
