A 2.5 million private jet is, uh, probably not new.
The smallest Very Light Jets, like the Cessna Mustang or HondaJet, start around $5 million new.
So you’re probably looking at a decades old plane, almost certainly not enough room to fully stand up, and possibly no lavatory.

My American cousin lived and worked in France as an engineer for several years. This is absolutely not true. He did make an effort to learn some French, but it wasn’t because of any pressure. He just wanted to.
