It seems pretty easy to get 200k from any LS engine, if you do regular oil changes and don't abuse it. IMHO, be easy on the power until oil gets to 180'F. It won't be long until we are seeing C6's with 300k.

The LT1's keep going and going .. the LS motors seem to rattle from their
first day, front seals apparently leak and are hard to replace (I have one
to do on the wifes 200k+ '99 SS, but reading made me fear doing it). The
belts seem to squeak constantly no matter what you replace/spray on it.
Thats from the '99, the '04 GTO seems to be the opposite, though I have
read the Aussies did stuff to them, but I dont know if thats true or not. It
is true that making it to 200k should not be an issue, but most LS engines
are going to make a symphony of sounds getting there .. or maybe GM got
their act together on the later versions.
My main concern with the C6 was the A6 trans. The 700/4L60 was about
a 100k trans behind a performance engine. A decent rebuilt would net a
150k span, but the factory ones didnt last.

07 C6 coupe
81K miles
She's my DD (100 miles round trip 5 days a week).
Only problem is 1 battery.
On my 2nd set of Michelin's - got over 40K on the 1st set.
Averaging just shy of 25 mpg (combined)
Love this car!

Mine Just hit 162,000 miles. It's a 2005 Z51. Nothing has really been replaced, no issues so far except for one of the tail light screws falling out leaving one of the tail lights dangling. (embarrassing)

Wow, it is great to hear these stories of 'higher' milage cars running great. I was getting a bit nervous because I heard the clutch is really expensive & had no idea how long it lasts under 'normal' conditions...

My 07 now has 100795 miles. Only real problem was the passenger side fuel gauge sending unit needed to be replaced at 80,000 miles. all the rest is just maintenance and service,
The spark plugs were changed once (They looked good and could have gone a lot further)
3 sets of spark plug wires.
3 sets of tires (looks like the 4th set will be going on shortly) Aligned every 8000 -10,000miles. (Cool lifetime alignments at Firestone!!)
1 set of brakes and rotors at 70,000 miles (replaced with Delco ceramics)
Coolant and rear end serviced @ 50 and 100,000
Trans serviced at 100,000
4 cabin air filters at (25,000 miles)
Oil and filter around 7500 give or take a little !!
Thats it !!
