In this area, there was a CL scam for Cummins 4bt and 6bt engines. We also had a toolbox scam. Both of these scams were followed by CL customers posting warnings.
I bought a Cummins 4bta engine. After seeing this engine run, we settled on a price of $3250. The seller's response was, "OH, not this engine, I will deliver the engine you bought, tomorrow." I offered to call the police. My son and I borrowed the seller's engine hoist and loaded the 4bta into my 2500 RAM truck, while the seller watched and protested. Once the tailgate was closed, I paid up and we left.
I get about 10 telephone and email scams calls a week. Someone with a South East Asian accent wants to help me with a problem I did not know I had. I worked with an electronics guy. His hobby is scamming the scammers. He likes to get into their systems and delete as many files as he can. He often locks the scammers computer making it unusable.
