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

My wife and I have been driving a Mercedes W247 200d for seven years now, with 93,000 km on the clock. The car is very comfortable even on long trips and economical. At the last service the pads of the electric parking brake were replaced; otherwise no repairs. We love this car.
