These are boosted beasts, but they are not running under boost all the time. Unless your "trackin" her every week, there shouldn't be any problems with proper maintenance. I drive mine roughly 1000 miles a year, mostly weekends, no rain/wet roads. She is cleaned/garaged/covered after every drive.
If people are looking for collectibility in this car, it will come with time and originality. The muscle cars of the past took 30 years to become collectible, as the DD's and boneyards consumed those that were not garaged. I feel that this new CAFE standard is going put the same collectibility with these beautiful machines. It will take a few decades for the value and rarity to show. Just be patient.
The values also comes with the buyer. The 07-09s are the originals (just as the 67-68s), and while they might not have the same handling and performance as the 10s and 11s, they are still the originals. I personally don't like the plastic side skirts and rear lower fascia on the 2nd gens, it really throws off the balance of the car (esp with the bright colors)... just looks cheap. Plus the hood extractor on the 2nd gens is ugly; otherwise, she a beautiful beast.
