I sold my mum's Rav4 with broken engine recently via Gumtree. Brought all the grubby con artists out of the woodwork; my phone almost melted from SMS messages with crazy low ball offers like "how much fuel in the tank? Give you a goat and a smile!" The grub that bought it tried to extort me for the balance of the rego and threatened me after the exchange was finalised, demanding a warranty! Part of me hopes he comes back, but after my last conversation with him I doubt he will. I "communicate with influence" due to various life experiences Considering all the hassle, Gumtree worked well for me as the vehicle was gone three days after I listed it. Caveat emptor; caveat venditor!
