Flat tire = hasn’t moved in a while
Some unspecified issue with the transmission that seller was told about = needs total rebuild or replacement
Price: $4,000, because these are hot right now, according to somebody
Includes picture of an ad posted by a delusional idiot in Iowa who wanted $9,000 for a roadworthy example, but no confirmation said car actually sold for that.
Other issues? Probably several, based on how cagey the poster seems to be. I wouldn’t be surprised if the air conditioning “needs a charge”.
