Ok, I'll be the odd man out and try to justify it using your car analogy. The tatula weighs in at about the high end of 7 ounces, the steez around the low end of 5. That's the difference of about...let's see...what's a whopper plopper weight(I picked that cause I'm sure we've all seen or own one,lol)? 1 3/8oz??? If that ain't right, it's close. So the weight difference is kinda big. Now, a viper, or vettez06 will run around 200mph, but getting above 240mph is a completely different story. It requires so many more horsepower for every mph over 240, then gets exponential around 260. A few production cars can do that:2 in particular the Bugatti veyron and the Hennessey venom gt. So much research and technology goes into every mph for those cars. Special paint,engine configurations, components that are super strong but lightweight,and so on. You can get a veyron for about $2,000,000. On top of that, Volkswagen LOOSES a few million on every car but it's their flagship. You sell more passats and golfs when you have the wolds fastest production car(not any more thanks to the venom).
So the steez is Diawas flagship. It says "look what our company is capable of." They made it that light without sacrificing quality. There are lighter reels on the market, but they seem to sacrifice components to shed weight.
the point is I'd love to have a steez the same way I'd love to have a veyron. Not for any reason other than it's a friggin veyron!
