I had an '82 mustang. It was mounted on a bobtail bronco frame and running gear. It had 38-18's on it and was the ultimate beach and surf car. It was quite a bit of fun. I had to get rid of it when I needed something more family sensible.
As for the OP, I have had my share of razors in many brands and sizes. I think some razors are slightly better than others. I have had many great razors that were far less money than those examples that shave as well. That is what the free market does. When I get even just a touch of logic to explain why, I'll let everyone know. A 7/8" W&B will shave the same as a 8/8" but cost half as much.
