Ya never know.
I seen a Craislist ad years ago for a 47' manlift for $500. Totally thought it was a scam. Resisted sending a reply. Finally sent a reply on hope it was real. It was. Legit deal , not stolen.
I bought the manlift for $500. No haggling over the price , just paid what they were asking.
I put a whole bunch of sweat equidity into it and about $500 in replacement parts. Got it looking good/ working properly.
I sold it for $11,000.
Nice flip/serious markup.
