SDL on Ebay

Thoughts on this one? No way in the world would I ever buy from Ebay without a thorough in-person check (as I would do on any other car ) but at this point just trying to gauge market value.

Gotta ask for service records - ANYONE can SAY a car was "meticulously maintained."

I don't understand the "A/C blows cold but should be checked." Huh? I don't know what that means - does is work or does it NOT work??

Obviously need documentation of the replacement of the rod-bender. Are the replacement motors subject to the same problem?
