I test drove one of the non-HO JGC's last night (4.7 V8), a 2000 with *apparently* 129k on the clock, which matches the dash, the interior (such minty minty fresh beautiful leather seats), and the body panels (oiled). The underside is pretty rotted though (all around the pinch welds, and the main supports from the frame rails were hole-poke-able) and needs lots of metal work/attention. It's up on kijiji for $3500. I have pics of the underside if anyone wants to check them out.
He said he's done almost a complete front end rebuild, but to me it didn't look like anything other than the front axles (new boots) and maybe drag links, I didn't look too hard after seeing the rust. The ball joints looked pretty crusty still, doubt they were done. Only a very minor PS seep, otherwise the engine seems dry. New tires on it, new muffler but just clamped in. The oil may have been overfilled IIRC, not sure if that was to hide noises or just an oversight...
But hey if anyone is looking for a project, the engine purrs like a tiger (LOTS of get up and go), the suspension (no creaks, no pops, very smooth, predictable) and brakes (tracks straight even with a quick stab) seem well sorted although a bit soft in the suspension department, but no surprise there for a GC. The front drive shaft was not in, but this has an NP247J - Quadra Trac II which are pretty good TCs.
I will not be buying it. The owner (Dave, a manager? at Meineke on Carling) is supposedly putting on new rockers and doing some underside work. Not sure how legit this guy is or the actual mileage Too far gone for me since I'm looking for a decent DD. Sounded like he just wanted to unload it.
Worth someone checking it out.
