Well since my old save was from over a year ago before I stopped playing ETS2 and have had trouble getting back into it because I wanted my mods back.
I want to make a new profile so I can start from scratch but at least not lose all I worked hard for with my old profile, so I can probably give myself a nice £2mil which is more than I have in the bank on the character, but less than if I added the amount my truck is worth to that.
I guess I'll "simulate" George Osborne's inheritance tax.
