Excellent truck, the Isuzu D-Max 3.0... less blah, blah, blah and more economy, better engine and robustness, and more comfort when driving

The whole "Toyotized" marketing thing is another story; it's a good vehicle, but it's given more fame than it deserves — very bouncy, unstable, I almost rolled one of them

I've had a Hilux 3.0, then a Mazda BT-50 2.2, but now an Isuzu D-Max 3.0... marketing won't fool me — body quality has dropped, electrical systems have many problems, and Toyotas have become more disposable in my view and according to five workshops I consulted... nothing like the Toyotas from 2015
