The seller reminds me of the guy I got my flathead from, he would just go wildy off tangent on whatever topic or question I had.
I looked it up and found the ad, and I see you're holding out on us- You didn't mention the PT Cruiser that can be had for just $250 more when you buy the "Nash" and the "single axis" trailer. Wild.
That has been for sale on Craigslist on and off for about 5 years now and the owner you cannot get a straight answer from him ever.
