We have a few 2.8 hilux's in the fleet at work and to say they are complete pieces of sh!t would be an understatement. Until Toyota sort out their DPF issues and the dashes falling out of them at least, I wouldn't recommend anybody buy one. The prado shouldn't have the dash problem but I'd wager the DPF setup is the same.
Our worst ute is 2 y.o. and just out of warranty (over 100 k.m.), had a new DPF under warranty which lasted 20,000 k.m., shit itself at 115,000 k.m., they charged us $7k to replace it and just last night it has gone back into limp with 100% DPF blockage again - not to mention using a tank of fuel to get to Gympie.
Being a company, DPF deleting is not an option for us, and having cars off the road all the time is a royal pain in the rear.
If that is a glimpse into your new future, please find one of the last v6 Prados and buy that.
