Looking at this 69SS..Worth it?

[68SS496]

Im currently in the market for a 69 Chevelle SS in Lemans Blue..I came across this one on the internet and was wondering if you guys think it could be original and worth what hes asking..The seller says it is ( mostly) original, and it looks like it could be, but there are so many scammers out there... there is also a build sheet that looks to be original he sent me as well..
