(Warning, old man rant)
Boys and their toys, you know what Freud said.
That car, designed to blast out the ears of the occupants, and anyone nearby, is just obnoxious. There's nothing I hate worse than sitting at a traffic light and having some selfish boor pull up with their sub-woofers booming and shaking my fillings. There's no need for it and it indicates a total lack of class.
That said, although I don't care for the looks of the HHR, I'm glad to see GM producing a practical car that's not a gas guzzling hog. The mileage could be better, but it's better to drive one of these than a Hummer or Suburban, the majority of which are driven by one person on a highway.
I feel the same way about the 'vette that was posted and all other "muscle" cars. People should be entitled to buy what they want, and the Government should not get involved, but there is no need for a car that can do 200mph for roads on which you'd be lucky to go 80.
A car for me is a way to get from point A to point B. I want one that carries the stuff and/or people I need in relative comfort, is reliable, and gets good gas mileage. The more I spend on a car, the less I have to spend on other things, or the longer I have to work before retiring.
I have had my head turned by the looks of many a car, but I wouldn't spend the money on them, just like I have had my head turned by a number of women, but I wouldn't trade the one who has stuck with me for the past 30 years.
