Used 2020 Merida Scultura 4000 with disc brakes for 1.2k AUD/812 USD

Hello, I've using my mountain bike to cycle and decided to upgrade to a road bike and found this deal on a second-hand marketplace.

It is a 2020 Merida Scultura 4000 with disc breaks and Shimano 105 groupset for 1.2k AUD/800USD. Is this a good deal?

Is there anything I should be aware of when purchasing a used bike?

Thanks in advance.
