Looks like the compnine vin lookup site is officially down. I hope it was just a hack or something but they have this message posted:

"These types of announcements don't come easy, but effective immediately Comp Nine will be closing its doors permanently. Thank you to everyone that helped keep the site going and for allowing Comp Nine to serve the community for so many years."

Been using that site for years and just yesterday it was up and running. Anyone know of another source for VIN build info besides a GM VIS report from a dealership?

 

I always wondered how "legal" their exposing of GM data was. I am not aware of any other sources for that info.
