If I may cut and paste my 2 cents here from another thread

And if I may add to the steel vs fiberglass debate, I am not opposed to fiberglass as a material, I am a huge fan of Ed Roth and his bubble top creations, which were made of fiberglass. (I had the honor of meeting Ed at a car show before he died) Fiberglass also makes cool grille shells with canted quads and drawer pull knob grilles. I also don't have a problem with really expensive cars, if I had 50 grand to spend, I'd spend it on old cars, too. The reason I'm building my car as what will inevitably be called a rat rod is because I like the way they look and I think the style is very creative. Something really different. It'll have 4 brakes and a steel floor, but it won't have much paint on it and it'll never be mistaken for someone else's car.

Rat rods are not by definition unsafe, and not all "rat rodders" hate every finished car on the road. It's the lack of creativity (off the shelf unmodified fiberglass bodies, 350 engines, boring paint jobs) that rat rodders don't like, and unfortunately, some rat rods are just as boring and predictable as the cars they were built to be different than.

I will always rank creativity above fit and finish, and someone will always disagree with me.
