I've had an Isuzu D-Max 2011 Crew Cab since new, first new car I ever bought. I've been very happy with it.
For what it's worth, in its fourth year the alternator failed. As I got the car on a novated lease, I had an extended warranty.
At the time, Isuzu's were sold through the local Ford Dealer.
I dropped the the car in, and a young mechanic drove me back to work. He said he thought that the D-Max was a good vehicle, and he was going to buy one.
I asked about the Ford Ranger, which was getting a lot of good reviews at the time.
He said "Put it this way, yours is the first D-Max we have ever had back for a warranty repair, and I can't say that about the Ranger."
