Im driving Hilux 2.4D for about three years and never had any problems with it.
My hilux have 180.000km and everything works like new.
Its very simple vehicle with pretty impressible storage capacity (up to one tone)
Now Im using it with stock suspension but next week I gonna change shocks for GAS Sachs (front) and GAS Gabriel(rear) so then I can tell you more about that.
But even with stock suspension Hilux is very nice to drive, you feel like you're driving corolla or so
The engine and transmission works very good, and the consumption is about 10l/100km (city) and about 8l/100km (90-100km/h)
The only dark side of Hilux is quite weak engine but off-road when you engage L4 on the transfer case it helps a lot.
So buy Hilux! Im sure you will be very happy with it!
