Wow, some good ones above.

Bob, - go ahead.. I already started the list. LOL

Wheelie Bars. Oh yeah, foolishness away from a track imo, I watched someone get stuck at a gas station when the rear tires came off the ground!
Ricer mufflers, up here in New England we still call'em Fart Cans. Now "they" have perfected the fuel load so when they take their foot off the throttle, it sounds like a machine gun going off! SIGH..
IFS without fenders... okay.. I guess it's all about "the look" , kinda goes with wheelie bars maybe? I HATE a straight axle on a car. Our 48 F-1 still has it's original axle, just awful!
OH - if you do the poll, it'll be a good way to see how many of us still look in here! LOL
Rat Rods, oh boy.... the "perfect rat rod", perfectly executed..???..?? Never saw one. I have seen many so called "rat rods" and the only thing different than mine was their flat black paint! But I get your point on the fan... kinda like a easy cheat or way out ain't it?!!??
Check writers.. who fail to credit the shop/builder, I'll agree with you. Someone has their car built, I don't have a problem! But acting like they personally turned every bolt/nut and don't acknowledge they can barely drive it.. that's just fraud or deception IMHO.... I am glad to see a pro shop built car. Love to look'em over. But I hate being lied to.!

My other "issue" with Rats as they're called, it's the one just purely built to offend. Assembled with zero knowledge of auto technology and basic physics. And I hate a rusty P.O.S.!
Thanks to all for sharing so far!
