Is this a good intermediate-level bike for trails and x-country?

Looking to buy a bicycle for riding intermediate trails (mainly flowy but occasional drops, etc) to replace my 20-year old mtn bike.

I don’t need the lightest or best bike but would like something reliable and versatile (ideally also for light urban riding).

This one has been listed for 1 week so I reckon I can barter even lower. Thoughts?
