FYI found some interesting information on the BDX armored personnel carrier that in real life Mexico bought from Belgium. They may actually be a real contender for a canon APC. They were originally designed by Timoney Technology as the Mark IV and VI for the Irish Army and then licensed for manufacture by Beherman Demoen in Belgium as the BDX.
The production of the BDX was completed in 1981 in Belgium and they were delivered from 1978-1981. There was a supposed to be a follow ons, including a 6x6 version of the Timoney Mk V and a new vehicle made by Vickers called the Valkyr but neither ever went anywhere (for one reason there was the big draw down in global purchasing due to armies reducing in size). Only two Valkyr's were ever delivered both to Kuwait before the invasion.
I could see in V1 the Valkyr going into production as the improved BDX and then seeing Belgium making the older version available for export. Or alternatively Mexico buying them new as their APC since export orders was one of the big reasons for it being developed.
