I am not actually, when buying a car for the main purpose being Daily Driver + Weekend Off-roader, I will always choose a Japanese make. We drive these cars daily and then at the same time push them in 40+ degree heat! They have to be tough and reliable. RR or Jeeps are good, but I have never come to trusting American/British makes just because the Japanese are second to none in build quality of a vehicle and they are inexpensive to maintain!
I had a 2005 Prado LWB for the past 3 years and I have very few complaints about it after 276K Kms. Just recently switched over to a 2006 Pajero SWB for a change. For the dunes I prefer having an old car with less computer management etc. It makes the experience on the sand more raw and in my opinion will make you a better driver, anybody can buy a 2019 Prado and get stuck and use Crawl Control to get them out. But if you're really into the sport of Dune Bashing I think knowing the methods/techniques of self recovery etc are just as important and this only comes with Experience. But then again the newer models are much safer so if you intend to take family/loved ones around everywhere the newer models are much better.
Lastly, in my opinion, I think any of the 4x4's we have offered in the market (Pajero/Prado/LC/Patrol/JK etc.) are all perfectly capable vehicles. Each has their own USP's but overall they all will run the toughest sands the Middle East has to offer just fine :D. I'm a strong believer of the saying "It's the driver, not the car". If you know your car well and how to take advantage of it, there is no dune that will hold you back!
Oh! Also this is my first post here and I hope to be seeing you guys soon on some drives. 😁
Cheers,
