I live in Tennessee and bought my bike out of Oklahoma, and drove to get it. Trust me, although I got to see the bike when I got there, I had the same feelings as you. There was no way in hell I was going to drive 700 miles ONE WAY without being sure it was 100%. I drilled the hell out of the owner, and got tons of pics of the bike. In the end there was no surprises. I only drove to get it b/c it was such a good deal and I couldn't find a good rate on a shipping company. Also you gotta watch those shipping companies, most of them will just piggy back your bike on the back of a moving van to fill up space, and sometimes it's a month before you get it.
I don't have the info, but there's also like private inspection companies that will inspect products like this that you plan on having shipped.
