Yeah, it's a nice car, but not really $100K nice, much less $300K nice. Let's face it, when you get up into that price range, there are a lot of other options available if you are looking for bragging rights. Heck, honestly, part the ZR-1 next to a Viper and see which one gets the most looks....
Hell there is a 2004 Lamborghini Gallardo for $130K located in Tampa being advertised. A 2003 Ferrari 360 Modena for $159K. Man, I like my vettes, but if I could get a Ferrari or Lamborghini for the same price, even used, that would be a no brainer for me. Yeah, the ZR-1 will be faster, but that is not the point.
The ceramic brakes would be wasted on me. And those that would track the car and need to replace those expensive brakes fairly often will likely get tired of that expense pretty quickly. Bear in mind that those EXPENSIVE brake parts are considered as "wearables" so they will not be covered under warranty. So how will one of those rotors cost you?
And as for the paint over the exposed carbon fiber, how many local shops are going to have that $60k per gallon additive on tap if you have a boo-boo that needs to be fixed?
Seriously, I was going to sell off some of my gun collection to buy this thing, but changed my mind when I finally read all the details.
