Seems they went for a drive yesterday. I got this email and photos:
Your dad thought you might appreciate seeing these pics from yesterday's trip up north. Asians got their brand new Pajero bogged. Three four wheel drives could not pull it out! All three of us began to dig ourselves in but pulled away so we wouldn't end up in the same predicament!
From a little of the offroading we did today, your dad also said you would probably enjoy it very much up here with your 4WD.







Looks like none of the vehicles are particularly equipped and it seems they tried to pull him out but were looking like digging in themselves so to their credit, they left it rather than do some thing stupid.
Never heard the end result tho.
