You might not like this, but I'd say it's not needed.
We (Landyzone) cater for Landrovers, not specific countries peculiarities. If you have a Landrover question ask it in the relevant forum, engines, Defender, Green Laning etc. I suggest that if a 'Bulgaria' section is added it'd serve no good purpose as you're the only person I recall to have ever requested it. You'd have to answer your own questions ....
