Buying from afar

So I found a car in another state I'm closing in on buying. The transportation part isn't a problem, I've shipped cars across country before. Its the money part. If we were closer I would show up with a bag o cash, do a bill of sale, get the title signed and drive off. But its 12 hours away. Its listed on For Sale: 1970 Dodge Charger R/T in Topeka, Kansas but I don't see where the have serviced to cover this part. Any ideas?
