I havent seen a 40k+ miles Z go for more than 18500... base model C5s are going for the LOW 10k range... just saw a 2004 (base model) with only 35k miles go for 14k...
you cant base values of collector auctions. NADA values are the ONLY book values that actually show TRUE/REAL auction values. KBB is garbage...
The market is trash right now. The values are just not there anymore. I have watched on ebay for months now. the EXACT same cars are still for sale at those 21 to 22k prices. Thats the difference, to ACTUALLY sale the car, you have to know what actually sold, NOT what is for sale.
I do feel like I got a good deal though. Given the condition of the car, and the history I am able to trace back.
heck.. if you want, I will post/show you SEVERAL Zs, under 60k miles for around 20k or less... they are very easy to find...

There are quite a few people on this forum that believe the 02 and 03 Zs had an issue with value springs. A forum member did a well documented study on it. I am sure you can find it.

what i'm saying is if they haven't broke you have no worry, simply change them if you buy it. those springs have lasted 200k miles and broke at 10k miles

To the op I changed the springs in mine myself within 6 months of getting it 2 years ago. It's not a difficult job if you are fairly mechanically inclined. LS motors are very easy to work on IMO. Coming from an LT1 they are a joy.

Thanks for all of the replies and advice. The forum is very welcoming with a wealth of knowledge! The dealer is holding firm at $24K so I'm probably going to pass on that offer. Thank you for the info zo659! Where did you find your Z06 randyfl? I live in Iowa and I don't think we have too many auto auctions around here. WHen I lived in Orlando they had them all of the time.

what auction did you go to? I have been to hundreds of dealership auctions. (easy for the public to go to as well) NONE have went over the 21k mark... heck just saw an 04 with only 30k miles go for $20,500. I didnt buy it because it was black.
I havent seen a 40k+ miles Z go for more than 18500... base model C5s are going for the LOW 10k range... just saw a 2004 (base model) with only 35k miles go for 14k...

it's also not easy at all for the public to walk in unless they are with someone who has a dealers license

exactly... clean nada trade in on a 40k miles z06 is right around 18k... which is what I paid for my Z....
a lot of people dont know this, but aution values DRIVE NADA values.. not the other way around...
etiher way, there are obviously lots of factors in the overall price of the car. I have paid more than nada value before, and I have paid less. IMO, not too many C5Zs are worth 20k+... they would have to be an 04, and have extremely low miles, to be much more than that...
maybe its harder in your state to go to an auction than. But here in OK, its VERY easy for the public to get into one.

The car you bought for 18.5, is this something you bought to flip or hold on to long term? I assume you plan to flip it given the number of auctions you go to.

2003s can have valve spring failure also, but it's not as prevalent as in the 2002s.
Sticky at the top of this forum. Member failure inputs tells the story.

The dealer had never heard of the problem, or at least didn't admit to any knowledge. He is really into Corvette's, his personal one is a C6 ZR1. I wonder if it is one of those things that are more talked about than actually happens. I've heard it manifests itself in about 0.5% of cars, but if it is your car, it is catastrophic. A new engine is at least $5k and that wouldn't include installation.
http://forums.corvetteforum.com/c5-z...-failures.html
And if the ZR1 has the same valve guide issues & valve heads snapping off as the LS7, better tell that dealer to log in and read up on people's actual experiences.

kbb is absolutely worthless. NADA is the only book that's based on real sales figures.
as for parts and labor the full valve spring set is $65 and full valve seal set is $40 + shipping has you at 115-125 dollars. labor will be $200 if you know someone and probably as high as $500-600 if you go to the dealer. it takes a highly skilled guy about 2 hours to do the entire job. one of the guys i know from our local track is a mechanic for a funny car team. was chatting with him about it and decided to give him 200 to do mine just so i could watch how someone that good would do it. he was done in 90 minutes and i sat there having a subway seeing how it went down. not really a hard job, i could do it having watched what was going on, just had never done an LS engine before and didn't want to overlook something or make a mistake on install. part that surprised me is these engines have no valve lash adjustment, you just bolt on the rocker bars and go. it's like grown up legos

Perhaps if I can find several 2002 owners in my area (DC, MD, VA) who are interested in replacing their valve springs, I can look for someone like the mechanic who did the work on your car. I'll even buy the subways for everyone.

eh... I have early build (10/01) 2002 model.. so even if I was worried, I am in the "safe" zone according the research you guys put together...
There are just as many failures with transmission parts, as there are valve springs issues. lets face it, drive it crazy.. and ANYTHING will break. But you cant worry about EVERY LITTLE issue... And with less than 1% of Zs with broken valve springs... thats a little issue IMO..
