Consumer Reports, JD Power, this report or any other is only as good as the data fed into it.
I am a CR member and take their annual survey. But they only want info on two cars (I own four), the newest two TVs, etc. So they are missing a lot of input. And a smaller data-set reduces the statistical relevance of the survey.
In addition, if you don't belong to CR, how do you give input?
Finally, so much input is subjective, not objective. What is serious to me may be a minor inconvenience to another. Or as we see on here, someone felt pissed at the dealer over a petty issue, so decides to lambaste the entire product.
It's all good effort, but I am curious when I see the 2008 results 65 repairs per year per 100 cars called average. As the OP states, the numbers are too small to be statistically valid.

With the 65 per 100, does this seem too high or too low for 3.5-year-old cars? For the typical car this translates to nearly two years between repair trips.

TrueDelta has updated reliability stats for the Corvette, based on owner experiences through June 30, 2010.
We'll have updates in November and February. With more participants we could provide more precise results and cover more model years.

Actually, I'm not sure you do. Anyone who signs up to help provide the data pays nothing, and this is the route over 99% of people take. The paid alternative primarily exists to provide an incentive for participating.

The 65 means that for every 100 cars there are estimated to have been 65 repair trips during the past year. This is the same as 0.65 per car. Since some cars require more than one repair trip in a year, about half required no repairs at all.
This is a big change from the past, when the question was not whether or not there would be a repair each year, but how many.

Any time. It's definitely not just you.
As for me, it took me days to figure out how to open the outboard air vents on the 2012 Ford Focus I had last week. There were thumbwheels to open and close the vents on the center stack, but none for the outboard vents.
Turned out that sliding the air direction tab all the way down closed the vents. Slide them up, and the vents open!
If even an air vent can be hard to figure out...

The real test is a lot more than 12,000 miles in my book.
Geez for starters my 96 4 Runner went 125,000 before $$ spent on anything other than tires and fluids. The exhaust manifold cracked. sine then The car is up to 177,000 with. No other expenditures, this includes still retaining original brake rotors and pads! I also had a Honda that went the same milage with no failures other than the interior just wearing out at 175,000 miles, it was a cheap 1500 S civic.
I am a happy owner of an 08 C6 but I would greatly hesitate to compare the C6 at those milages.

My 05 is running great with 120,000 miles on her.
I took here down some remote dirt roads in Wyo yesterday for an Easter drive - she even handles those just fine.
This car is not a delicate flower!! I drive her year round in snow, on dirt, gravel, mountain passes, etc. Still looks darn good as well. :-)\
(I have ripped off the front lower air dam a few times, but not hard to replace)

Thanks for following through and updating the data. Like with the government issuing their economic data I always take it with a grain of salt. Economic data is released, some people react based to the data and then the next month the government revises the data. 
Good on you....the Corvette is made to drive! 
My 2005 is a track car with far less mileage but what miles I put on the car I consider 'hard' miles. I beat on the car week after week year after year. A few very minor issues aside my 2005 has been incredibly reliable!

Actually the graded gravel road was far worse that the just the dirt rutted one with grass growing down the center. The graded one was washboarded and shook the heck out of me. LOL!

Sweet! I would be scared to death to race on a track.

We have updated reliability stats for the Corvette, based on owner experiences through June 30, 2012.
Repair frequencies, in terms of repair trips per 100 cars per year:
2008: 26, better than average (and better than earlier, kinks now out?)
2007: 20, better than average
2006: 35, better than average
2005: 8, better than average, small sample size
We'll have updates in November and February. With more owners involved we could provide more precise results and cover more model years.
