BMW e92 320d in 2024

[Jcp045]

Potentially buying a 320d e92 next week. This particular one has very low mileage at 30k. As this is my first diesel what do you guys think of this? Is it better to get one with all the maintenance already done or start fresh with one that hasn't been touched?

I'm assuming it has been sitting for a good few years so would that affect?

Also what maintenance and mods would you do straight away?

Cheers
