Hi @ZULFIKHAR NAIYAR
Go for a white LE with 18 inch wheels for the following reasons
1- you will need each and every hp and torque you can squeeze out of the LE VK56VD engine. This is a heavy beast and its power/weight ratio isn't the best
2- you need 18 inch wheels to maximise the tiers sidewall. So at least start with the OEM ones that come with LE version. My tiers recommendation is 275/70R18 that comes around the same diameter as the stock ones
3- the Nissan Patrol is on every corner, and hence the scrap market is full of spare parts. But 99% are white cars. So if you're ok with a white color, it will save you some painting jobs
4- LE comes with conventional suspension system (springs, dampers, and sway bars). Its easier to repair or modify than the HBMC that comes with Titanium and Platinum versions
The number of KMs isn't really indicative for this car as much as how well its previous owner took care of it. If you can find a GCC one with agency service history then your good I believe. Nevertheless, this beast isn't gonna be easy on the pockets when it comes for mechanical repairs. On the bright side, again, lots and lots of 2nd hand spare parts
If you get the LE version, the bumpers can survive newbie and fewbie drives. But you will need to figure them out afterwards. Tiers, skid plates and clearance, other than that, you wont need any mod unless you wanna go dunes jumping
I personally drive a 2019 Patrol and its a blast once you figure out how to control 3 tons on sand
