Which Z06 should I buy
Hi Guys
I was going to by a 2000 Convertible but decided to go the Z06 route. My question to you guys is which year should I buy in the 2002 - 2004 models? Is there a difference? I know the 2001 has less HP and didn't come with HUD but does it matter in the 2002 -2004 models.
Thanks
Dave P.
PS: If anyone has or knows of a nice low mileage Z06 for sale drop me a PM or E-mail at prine1@***.net or phone me @ 623 340-2379

04's had an improved fuel system which carried over to the C6.
Here's the full list, most are just differences between 01's and 02-04's
differences between 2001 & 2002 & up:
1. The LS6 engine standard in the Z06 increased from 385 to 405 horsepower. Torque increased from 385 to 400 lb-ft.
2. Front fender badges for Z06 models included the 405 HP designation.
3. LS6 exhaust back pressure was reduced by 16%
4. Cam shaft was redesigned resulting in increased lift and a 5% increase in air flow
5. Valve spring material composition was changed to increase seat load by 14%.
6. LS6 intake and exhaust valves were a new, lighter design.
7. The valve train weight was reduced by 0.81 pounds, which improved valve seating at high rpm.
8.Airflow over the LS6 MAF sensor was increased by removing grid work
9. MAF software was re calibrated
10. LS6 air cleaner housing had a larger intake
11. Wheels looked the same BUT they were cast spun instead of forged for a weight savings of 1.3 pounds per car
12. rear shock valving was changed
13. Improved clutch
14. Thicker front anti-sway bar
15. New front brake pads
16. HUD was standard (HUD was not avaliable in 2001 cars)
17. 2004 introduced a new fuel system which carries over into the new C6.

The 04s also had upgraded shocks over the prior years, but these can easily be bought and installed on an 02-03.
I agree with the above recommendation to buy the newest one you can afford.

Which Z06 should I buy
Thanks Guys
The tranny thing is interesting. I'll have to check into it. Now I just have to find the right car. I found a 04 in Vegas for $35K but was a day late. Should have jumped on it when I had the chance but was waiting to hear on the 2000 Convertible.
Thanks Guys

I am biased, but, for me it was an 04 CE Z06 or C6. Like others have said, they retuned the suspension(shocks), upgraded some tranny parts and fuel system. It was a car and driver 10 best. It was the last year of the C5 and the most refined. Even if it is little improvements, it's still improvements. Just my .02! That being said, you cannot go wrong with any Z06! Good luck.

GM will say the filter is good for life. I change mine every season.
The 04s also had upgraded shocks over the prior years, but these can easily be bought and installed on an 02-03.
