Need advice buying a car long distance

I have purchased 3 cars off of here, a 71 dart, non running project, pm back and forth 4 a few days to get a "vibe" was a good deal, paid cash when he delivered it, a 70 duster from up in pa, same deal, lots of pm back and forth, lots of pics, sent him a certified check, had it shipped, and 3rd deal went all the way to Illinois and met the seller, paid cash and hauled it back home. All 3 deals went well
