I know this was tried a few years ago, but a fellow Caliber SRT4 owner called Chrysler customer service and found out the production numbers for the 2008 SRT4.

They have been trying to figure out the production numbers the same way we have and just now got the confirmation from Chrysler.

Anyone want to try tackle this again?

Attached is the letter from Chrysler about the 2008 Caliber SRT4

With all the changes there, maybe this information is open for us SRT6 owners too??
