I recently purchased a used 2008 Jeep Grand Cherokee Laredo. This is my first Jeep. Being a used vehicle it didn't come with much documentation other than the owners manual and a CarFax report. I contacted customer service at www.jeep.com
and requested a copy of the factory build documents on this Jeep. I provided the last eight digits of my VIN. They sent me back VIA email the complete factory build report for my Jeep. Now no more guessing what type of this or that I have on my Jeep.
This report is detailed and the only thing they dont tell you is the cost of the Jeep. This info my have already been posted. If so then my appologies to the original poster.
