In Europe most likely, and the lower 48 US, maybe. Definitely not a factual statement in most other parts of the world.
So, if I buy a new Cessna 172 for a trainer in England, or Spain, or such, it will have an HF radio?

As far as other than the lower-48 in the US, light aircraft in Hawaii don't have HF, and as far as I know they don't in Alaska either. In Alaska sat phones have become the backup for VHF.

Having said that control towers in the lower 48 transmitted on LF (below the AM band) as well as VHF well into the early 1960s. It was common in the 1930s and 1940s.
