Finally getting around to selling the suburban. Got a text from a "marine engineer" asking questions. I responded that they should call. I have a mil spec flip phone, it sucks when it comes to texting. Said they couldn't call he's offshore. Ask a couple of detailed questions. then ask if a moving company could pick it up? I said yea after he paid me, but asked how he was going to sign bill of sale. Said moving company has power of attorney. This is a scam right?
