    Edited on 08 November 2010 with inputs from Mr.Sudhir Kashyap on Facebook

    The last production for defence supply was in year 2006, for simple reason that the vehicle did not meet cmvr -emmision norms and therfore had to be discontinued
    The reason for this vehicle for army use was primarily an alternative to Earlier jongas, and whereever these vehicles performed they were literally an TORTISE… to move on to any difficult terrain.
    it was somewhere in UNMEE (united nations mission in Eritrea and Ethiopia )where these tough riders were being used in desert , and extreme conditions,with day time temprature ranging to 50degrees(BADA-) , i had the privelage as a invitee by the Indian forces for the establishment and training for repair maintainence of these small 4wds.
    These were a good competition to Land cruisers ,which were offcourse a comfort vehicle but did not dare into tough areas where these MM550XD, dared.

    Thanks a lot Sudhir sir for your inputs.

        Hi George, I’m pretty out of touch with the current prices of MM550’s but that said, 4.00 Lacs seems to be quite a high price for a MM550. But if its an NCGS which came after 2004 and very well restored, then it might make sense. But again, without looking at the vehicle, its difficult to even make an educated guess.
        My contact details are harjeev (dot) chadha (@) gmail (dot) com
        There are army disposables available in the scrap markets in Delhi but as I said, I have no idea on the current pricing scenario for the same.
        Cheers
        Harjeev
