Stock for stock the '02s are quicker. I've seen stock '02s in the 11's, the best I've seen a stock '01 run was like a 12.4.
The biggest issue with the '01s is the oil burning issue.
I know all those stats and more. Like I've said I've DRIVEN hundreds of C5's and tens of C5Zo6's...... so... you showing me magazine stats with miniscule 1/4 mile differences made me chuckle.
Magazine articles...

And by the way, the oil burning issue really has nothing to do with the rings... Do a search on corvetteforum... this is wayyyyy old. All LS's (as I'm sure you know) burn oil if rpm is kept up... it's just that the '01's got lots of press so it sticks in people's head... it really has to do with the pcv system, and there really is no cure, changing rings to '02+ will NOT solve the issue. Like I said, this is a long standing issue explained many times.
In the end who cares?
To the original poster, the prices are not going to drop much more, rule of thumb is that a low mile Corvette never goes below 40ish % of it's original price.... regardless of year. A Zo6 was roughly 50K new, you do the math. Same thing with C3's C4's until it's time to appreciate after 25 or so years.
A 1/4 a second in the 1/4 is far from miniscule....and who was talking about magazine articles, I never said that once? I said I have SEEN those times.
Many do, that is why the '02-'04 is more "wanted" they had many upgrades and fixes. The guy asked, I explained. If your buying, like I am the '02-'04s are the better choice. It's the internet remember? Chill out....and stop being so defensive. We're all LSx guys here, no need to be so sarcastic....

FWIW.... I bought my 1 owner 01 Z06, which doesnt burn any oil at all, in January 07 with only 17k miles on it for under $25k, so....
And to touch on the "differences" between the 01s and 02-04s.... I have quite a few friends around me with the 02-04s and "performance wise", there isnt a huge difference. Ive actually dynoed higher then a few of them. Mine dynoed 352rwhp/352rwtq.... On 2 different dynos. Weve raced numerous times and the only time you will see a big difference in the 02-04s, not all but most, is above 130mph where they begin to pull maybe a 1/2 car at most, but.... How often will you be up there?
Just change the cam and youll solve the problem quick!!! I wouldnt get too caught up in the performance hype though. Any vette, Z06 or base, is gonna be a fun *** car.... With tons of power, so.... Just make sure to be patient and find the one you want.
Might end up selling my F-body after college (4 1/2 years from now) and getting a C5 or C6.. By then I will have probably $34k to spend on 2 cars (keep in mind one of them will be a DD winter beater) plus whatever I get for the T/A
Want a Corvette because they just look more professional, and ride better.
