Is the deal on this 5800X3D PC suspicious?

Found this offer on my local marketplace. It's a used PC, and he's selling because he's downsizing.

GPU: RTX 3060 12 GB

CPU: Ryzen 7 5800X3D

Memory: 32 GB Corsair 3600 MHz

Mobo: Asus B550M-A

SSD: Samsung 980 Pro 2 TB

He listed it at $880 CAD. He dropped it to $700 (after 4 days as I was watching the listing). I offered $600 and he took the deal immediately. There was no counter from him at all. We're now trying to figure out a time to meet this week where I can check the specs.

My gut tells me this is too good to be true. Does anyone think I'm missing something here? The pieces are worth more than $600 if he pieced it out. The 3060 + 5800X3D is probably $700 alone right now.

Am I just out of touch with PC prices?

Thanks in advance for any help
