Twojeffs at the inteen site have a collection of buyable aspiration/career rewards which can be found
HereSeasons version is Bon Voyage compatible. As far as I know it is working fine but if you experience problems with his version there is support available at the inteen site.
If you cannot download or can't reach the link I put, you will need to register at the inteen site in order to be able to download it. Registration is free.
ETA: There is a cheat you can use that permits you to add as many aspiration points as you want, it is:
aspirationPoints 5000 which works for the selected sim. The 5000 can be change to any value you want. By giving them extra aspiration points it does unlock the aspiration reward you want.
