Looking at a '97 GQ II with the 4.2 EFI Auto. Does anybody know anything good or bad to share? I've owned a GQ before but it was the TD42. Mainly want to know about the engine/gearbox.

Engine/Gearbox is essentially the same as the 4.2 Diesel. If you cant bust the diesel , you wont bust the Petrol.

The EFI is better then a carby , but still pretty thirsty vehicles.

Quite a few run on LPG , but , there can be head issues doing so.

Other then thirsy . . . tough as.

Yes thirsty...
Expect an average of 21 litres per 100kms....

I have a 94 one has done 165 ooo and seems ok to date. Average about 18l/100
Heaps of power, the Auto runs downhills. stick a gearmaster in it and works great up and down.
Dual battery can be a pain as it will only take a small 8 inch cradle against firewall (unlike other models dsl and carby) where you could put it next to overflow.

Thought about trading mine and going to a newer GU, but just couldnt see any gain, so I hope to be driving mine for a few more years yet.

and a bit more:
had a trany service about a month ago and they said it looked okay. I was pleased cause I use 1 and 2 a lot.
I split my exhaust last year on corros, rust builds up in the waddings (white stuff) inside the heat shields. cant really check for it though.
if it has a clunk/rattle check that the heat shield plate near the cat is secure. The brackets break. Nissan fixed the prob in the GU (same way I did) removed the heat shield (lol) or can be held with wire.
Also I have been using pulp (98) and running my tyres at 36-38 for highway runs. Got around 16-161/2 on 3000klm highway trip.
The trip meter can get problems, gets stuck when it winds to 9 and 0. This also stops the odometer. Mine comes and goes. It can be fixed for a couple of hundred dollars
So considering the age, the milage and what I have put it through I think they are great

have a look here for General GQ stuff.

The autos are about $3500-4000 for rebuilds. From a poll we ran on the GQ forum, majority of people get 20/100 or worse.
