There is a lot of difference between the CJ7 and the M151/Mutt/Commando and you can't compare the two by any means. The CJ7 is a complete 4x4 vehicle which if done properly, will stand up against modern 4x4s/SUVs both on and off the road. The Mutt is a unique vehicle which has limitations in terms of its restoration, modification and use....
The restored CJ7 will invariably run a Toyota engine and perhaps gear and diffs too and will be much more expensive than the Mutt. A full and proper CJ7 restoration can cost PKR 700-900k in this day and age while a Mutt can perhaps be done much more cheaper as you have to mostly run stock parts on the vehicle....
