A little help checking out cars out of state

[centroid1]

I'm searching around for a nice 93 300D and I'm seeing a few here and there. How do people check them out from other states before they fly out ? Last time, I bought one in CA and relied on photos. The owner was willing to take more pics and brought it to a mechanic after I saw the photos.

This time it might be a nicer car and I want some eyes on it before I figure out if its a real potential. So here are the questions:

- does other forum members ever volunteer to check it out ? What's the etiquette for that ?
- is there a reliable car checker service to use ?

The intent would be to check it out visually up close and then I'll send the car to a mechanic for inspection.
