Has anyone ever bought a vehicle off fb marketplace place?

I’ve been browsing marketplace recently and I almost think everything has to be a scam when it comes to the vehicles. I’m seeing deals that are exactly what it sounds like too good to be true. Some examples are a 2024 Silverado 2500 with lift kit and aftermarket wheels for 31k, no accidents no damage and only 20k miles. I even saw a 2020 McLaren 600lt spider for 48k like how… has anyone ever bought a vehicle from marketplace and it turn out to be a genuinely good purchase?
