If the GM boys really do nose around here I hope they read this.
First off, I'd just like to say thank you to the powers that be for giving us the Camaro back. It's been one of my dream cars for 20 years, and the chance to make that dream a reality is something I thought I'd never have again. Please, take your time and get it right. I'm OK with waiting 2 years or so. I'm not OK with you half-assing it and rushing it to market riddled with problems. So get it right. You have no room for error.
Second, your other cars have been improving steadily over the last several years. The new Impala, while basically a stopgap car, is a good stopgap car at least. The new Saturn Aura is a really nice piece of machinery. The Kappa twins are phenomenal little roadsters. The new SUVs and full-sizers are top-shelf. However, I think you should do something to prevent backsliding into your old ways (as large companies are want to do once they think they're out of danger)
Find yourself a late-model J-body--a 2000+ Cavalier or Sunfire. Park it in your lobby in Detroit. (I have such a vehicle, if you're interested in taking me up on my idea--send me a PM, make me a deal!). Put it there to remind yourselves of what your company USED to be known for--cheaply-built, poorly-designed cars designed by committee and built by accountants. For added effect, cover the hood in black spray paint with the words "NEVER AGAIN", to really hammer the point home.
Your engineers walk in every day and see that pile of junk and they'll say to themselves "No way am I going to be responsible for something like THAT! I want to design a GOOD car!"
