1970 Ls6 Convertible

True, and I'm certainly not saying I've not owned some cars that I thought were completely legit and that had nothing more than title searches. However I didn't pay what the cars are "worth" today, and when sold they weren't sold for top dollar either. I think there are a lot cars without factory docs that are legit, but if I'm looking at the "big picture," I'm concerned about possible re-sale (never know when I might have to sell..)so IMO factory docs are the only way to go. Yes buildsheets can be faked, but if you educate yourself and research what original docs look like, you won't get burned..The materials to fake them aren't available (the actual sheets are distinct plant to plant) and the way the different factories coded the options and the fonts they used are unique plant to plant..With POP's the materials and "look" are universal and they have been avaiable for sometime..A POP "made" 15 years ago, can look aged and will appear original. Since there isn't any "special" wording, unique paper or type font, I personally don't think they can be used to validate a car. They are nice to have, and in conjunction with other docs can further lend credulence the car is legit, BUT they don't validate by themselves. Same with other non-factory docs...Just my opinion..
