Ive always had Isuzu crew cabs as my every day work and social vehicle. At present I have an auto 2017 plate which I bought second hand with 32k on the clock about 5 years ago. Not had any trouble out of it at all. That's my 4th Isuzu, including a new Rodeo in 2007, which I ran up to 90,0000 and part exe'd for a 3ltr.
Second hand prices on these are mad, I have been contacted by Isuzu several times and asked if I want to sell it or part ex for a new one, which is over 50k now.
I wouldnt buy a Ford Ranger, too many issues with them. One client/friend bought a new Raptor. 6000 or so miles, engine blew up. Another friend 2ltr Ford Ranger, oil pump packed up 600 miles from home, seized the engine. And my freindly local mechanic has had many in with head gaskets blowing.
I admit I am a bit of a petrol head, and have a second car on the drive. But if you look hard enough you can still find a bargain or two.
