He just responded with:
So, help me. What would I reasonably like to know? Here are some thoughts:
Why was it taken off CL and the price raised? (Probably not reasonable to expect him to answer?)
You said "It runs", but does it run well enough to get on a trailer easily?
Why was it parked?
Beyond a tuneup, is the engine solid? Does it use oil?
You said "Need it gone." But I'm in Oklahoma, so how soon would I need to pick it up?
Do you have a clear title? (Probably the most important question.)
