Here's something you can't get in pictures: Smell. We bought a Camaro in 2001 on Ebay, looked great, low miles, plenty of docs. Decided to just have it shipped since everything looked good. When it came off the transporter, we were so happy until we opened the door and the smell of urine poured out. There was a mouse nest under the back seat and in the cowl. In hindsite, we were happy that we actually got a car at all, because if a guy is a big enough scumbag to not tell you something like that, anything goes.
If you're paying very much for the car, I have to say fly out and look it over, and take a good whiff, based on my experience.
