A.a brother. So, About dalas in general, one thing you should know is that comfort is not what they are built for. Most dalas have leafspring suspension at the back and without any payload they tend to bounce around. Powerwise you can expect great torque from dalas. They can pick up and go from any speed when you put the pedal down.
The beauty of a pickup truck is in its utility and robustness. you will feel this in the drive. It's a go anywhere car with utility like no other segment of car.
I have a 2016-17, 3.0 D4D. And like you this is my 1st SUV or dala. I was looking for 2005 prados but when i sat in this model hilux my decision quickly shifted from old prado to this new dala. It's been 2.5 years since my decision and I am happy as can be. Love driving it. driven it on Mountains and in city. It's much better than vigo in comfort and feel and general design as well.
If you can find a genuine 3.0 then it would cost a bit higher than your budget i.e. 90lack or so with mileage under 1lack kms (genuine).
If you want more power you can tune hilux to get heap more torque and a lot more horsepower. I have not felt the need to do so yet. I only have a throttle controller installed which eliminates the turbo lag a bit.
Also tons of aftermarket suspension available for revos. Optimal comfort can be achieved using reservoir shocks.
p.s. 2016 PKDM hiluxes came with Thailand made suspension which is much more comfortable than the 2017 suspension made by agri autos in Pakistan. The local suspension has been stiffened to accommodate bigger payloads, i.e. lots of guards in back lol.
Tundra is a bigger vehicle than hilux and parts will be an issue. Its going to be much more expensive to maintain and maneuver in the city as well.
With hilux, i find it hard to find roads open enough to give it WOT.
Let me know if you need any more info on 3.0 D4D hilux. I have a Revo i.e. fully loaded trim.
