We have ridden the performance wave, way past reality and now will have to let things cool off in the performance arena. I think technology will have to catch up to the brute force of todays performance cars and that will take a few years.
Those who think they will be buying a ZR1 for 5K-10K off window will be waiting a while (and I don't mean 6 months). This car is the last of a breed and Jay Leno will tell you the same. Get 'em while you can boys and girls cause the next cars coming out of Detroit will have the equivalent of the coffee cans of the '80's under the hood. I predict it will take about 10 years or more for technology to catch up and give us a car we really want. If I'm accurate the ZR1 will be worth whatever you paid for it. (maybe the exception will be that guy who paid 1 million for his?)
