Mahindra's last flattie or the last production flattie in the world, the Major, went out of production on 30th September 2010 citing emissions, safety, noise compliance etc. The above image is one such made in that era for a foreign military's parade needs. It was a Euro 2. Another reason for discontinuation was to justify Thar brand volumes so it would at least be viable for the management to keep in production. That decision resulted now in Roxor happening on US soil.
With tooling mothballed/scrapped & lines changed, highly doubt any flattie be minted again at Mahindra. The Roxor happened only because it's a vehicle still in production elsewhere.
Or get one of these and fittings and mount on a Roxor chassis. it's the same thing underneath. Entire thing be a 1 grand job.
