I'm looking at an 07 Z06 with 16k on it. I will be trading in my 2013 ZL1 Camaro (600 RWHP). Thoughts? Anything to look for on the Z? The Z06 is at Bridge Auto in Berlin NJ asking price is $33,995. Take a look let me know what you think. Thanks, Bill
She's a beaut! You know about the cylinder heads on these LS7's, correct?
As for the price, its not a bad starting point for the asking for an '07 with 16K on it...I'd try to knock a couple grand off that, maybe more if the heads haven't been addressed (I'm assuming they haven't).
Get the Z, I just bought my first one a little over a week ago and love it. Had a 650hp 5.0 coyote before and was still getting walked by Z's with little mods. Probably be about the same with the camaro given the weights are close to a mustang. Find out if its had the heads worked on to fix the valve dropping issue, if not make that your first mod. Other than that i would say just make the usual checks as with any car, (oil sludge, rust underneath, interior condition, etc...), and the LS7 is a little noisy, you might here some ticking or a mild sewing machine type sound. I heard it on 2 different z06s i drive and a couple of speeds shops i called said that the sound was normal as long as it wasnt extremely loud. Good luck!
Very good price. I have same car with under 10k miles and love it!
If tires are original they should be replaced regardless of tread depth (if original they will have "TPC Spec" on the sidewall).
Check the VIN history at a GM dealership and through CarFax.
Early 2007's had potential failure of rocker arm bearing end cap retainers leading to the bearing needles coming out. Would be a low mileage failure so not likely an issue on this one with 16k miles.
Valve guide wear is a popular topic on this forum and apart from a short period of time after 2007 when Linamar admitted a quality control issue with maintaining concentricity of the guide to the valve, there is no conclusive evidence that all LS7's are susceptible to valve guide wear. GM has produced over 30,000 LS7's. Plenty of debate here as to what the actual risk is to every LS7, but no thorough data summary of failures in stock engines has been tabulated. Just lots of anecdotal evidence. You will have to decide for yourself.
If the car was built before April 2007, update the rear shocks to PN 25819268.
Good luck with your decision.

On my 2008, which I bought new, the original heads and the heads that replaced them were all found to have valve guide wear out of spec. Both sets were covered by aftermarket warranty. There's a very long list covering all years that shows how many guides have been found out of spec here at the forum. It hasn't been updated for awhile, so it's far from complete. There are also some informative links and stats included within for anybody who wants to know the truth. Here it is- https://www.corvetteforum.com/forums...-registry.html
Please don't lead new owners into a false sense of security. With over 80% of the heads inspected found out-of-spec just on this forum alone, which is a small sub-set of all LS7's, that's far more than "anecdotal evidence".
OP, have the heads (guides) checked for wear as soon as humanly possible. You are well within the mileage range for a potential failure. If a wiggle test proves there's no problem, great, rock on. And despite what a GM dealership tech may tell you, you do not have to pull the heads to properly inspect the valve guides - that was a transparent ploy to avoid paying for hundreds of pairs of cylinder heads to be re-worked or replaced on GM's dime.

Katech says otherwise look at the thread special.....you are correct you do not have to remove heads for testing.
I wouldn't touch it. It appears to have been seriously modded(evidence of a centi and also headers, so also a tune).
Radiator shroud missing( and you can see the pavement) meaning that you don't have any idea as to it's cooling ability, or it's high speed stability or front brake cooling.
You have no idea what you are buying with that car, IMHO.

As someone who bought a low mileage Z less than a year ago (with head fix and other mods I was going to do) that is a great price so makes sense what you say.

I agree. There are many, many other Z's available with same mileage and stock. As mentioned when negotiating, reduce price for heads and tire replacement.
I would steer clear also unless you can get all the records for what has been done and undone on the car. And I agree it may not run cool with the radiator shrouds missing and that big hole in what it does have. Price would be great with records.

Do yourself a favor and RUN... don't walk from that car!! It is gorgeous on the outside
(cosmetically) and very aesthetically pleasing. 17K @ $33K is a good starting price. BUT all of that being said, that car has definitely had a blower and probably was dumped by previous owner.
Too many other nice C6Z's on this forum, CL, Ebay... I would start there.

Well said.

OP, look elsewhere. This car may look nice on the outside, has an attractive price, but almost too attractive considering the mileage. That and the underhood pic has my gut saying something is off.
This is an example of why I don't like to buy somebody's else's heavily modified car. Be careful of the mods that you do because you'll more than likely lower your resale value. Your LSA ZL1 is a better ride, just clean your wheels and you'd be happier.
