I recently purchased 2008 Chev Tahoe Z71. I went to CarFax website to get additional info on vehicle and to find window sticker. Window sticker was not available & website that is posted on this forum did not pull it up, only stated file not available. CarFax website states that my vehicle is LS, when it's Z71 package based on LTZ model. I'm not sure why CarFax website showed different model version of my vehicle & my mechanic verified that my Tahoe is Z71/LTZ version, so I find it strange that CarFax shows it as LS. Also, does anyone know how I can obtain copy of window sticker for this vehicle? Thank you.
