Re: How to figure out build date
There is an "insight" web site where you can plug in the VIN and see exactly when the car was built and delivered... but we are not allowed to post the link in this forum.
The dealer should be able to tell you build date by looking in the same system, but usually its not posted on their web sites. You may be able to get it from Jeep customer service
VIN numbers above 706000 were delivered starting early May. I've seen some Vin 605000 vehicles built early Feb, the upgraded RHR started to be installed mid January. So you probably would be safe with a 730 in a VIN higher than 605000 then verify by looking at the drivers door, the sticker will have the build date.
If you become a site supporter you can see Milous's tracking pages and find the VIN numbers corresponding to build times.
