The 4.0L is a really a GOOD engine, I would say it is like the old JOHNSON/EVINRUDE 150 V6 loopers. Not the most powerful, not the best on gas, but just seems to run forever with a little bit of maintence and care. They do tend to be noisy when cold as the inline 6 design is prone to piston slap, and they are very unforgiving to being run hot(235 is the limit). The big down fall to them in the GRAND CHEROKEE is the trans that CHRYSLER put behind them in the GRAND. They used the old style CHRYSLER 4 speed slush boxes and many of them fail around 60-70K, but most all of them will need work before they hit 125K. The smaller CHEROKEE doesn't have this issue as they used the TOYOTA trans.
What year are you looking at?

I've got a regular 96 Cherokee 2wd with the 4.0HO. For what I've put into it, its probably the most reliable vehicle I've owned. Its got 185K on it now, I've never let up on it. When my Ford 150 Van motor blew up at only 100.000 miles, I threw all my tools in the Jeep and worked out of it for over a year. Its by far one of the toughest vehicles I've owned. I've put fuel pump in it, new radiator, brakes on all four corners, regular tune up and oil change, transmission fluid. Had the crank position sensor go out. I was able to fix it all, pretty easy car to work on. I'll probabl keep it till the wheels fall off

They're pretty good vehicles with the exception of the trans being known for going out in them in the milage I posted earlier. Also rear ends in the later grands like the 04 were known to be a bit noisy.

Like Spare, I've got a regular Cherokee. 1998 with over 160,000 miles on it. Used it this last summer to go to Fla and pull my boat home. 1600 miles each way. I've really never had a problem with it, other than a blown upper radiator hose where it rubbed on a bolt over time. I just change the oil when it's due and do the normal plugs and wires stuff. It's got a distributor cover and a coil, so you need to change them too, but that's it. They run forever. You can expect 300,000 miles on average from the engine. It is, undeniably, the most reliable engine I've ever driven.

Not on an 04 it doesn't. 98 in the grand's and about 00 in the cherokee and wrangler they went to a one piece coil pack set-up with 3 coils all mounted in a large pack that bolts to the head right over the top of the plugs. Just make certain to only use the correct CHAMPION plugs in them as I can't tell you how many of em I fixed by simply changing the plugs out when people would put in bosch or NGK.

The best thing about the Jeep GC is the 4.0 motor as Ferm and others have suggested. My wife's vehicle is a 2000 GC with 4.0L. We only have about 38,000 miles on it, otherwise I would get rid of it. The transmission sucks. The brakes suck. The weatherstrips around the doors suck. The suspension sucks,. The gas mileage sucks (although she doesn't drive far enough for that to be a real factor for us). Not sure if I've left anything out or not, but I would certainly not buy another one. We did have a 1997 GC before this one which seemed better to me, but that one was in a bad accident.
I know others will disagree with my opinion of the Jeep GC, but I'm serious when I say I would never, ever buy another. I could go into detail about each item I've listed, but I think you get the idea. Let me know if you do want more info.

I did not want to rain on any ones parade but since Chum let the cat out, in my family we have had two of the Grand Cherokee's and two of the Cherokee's of the 90's and 2000+ vintages and every one of them were POS.
Transmissions that went at early mileage's engine that went early, one mechanical problem after another.
It's a shame cause I always liked the looks of the GC's myself.
Now the older Grand Wagonneer I think they were called from the 60's thru to the late 70's, maybe into the eighties I am not sure when they changed the line, were actually very reliable and tough, one of my friends who is a professional guide and outdoor writer had well over three hundred thousand miles on his and was still using it as of a couple of years ago, never let him down once in all the off road and traveling he did with it.

late 90's Tahoe/Suburban, they'll get around 18 on the highway. Mid ninty's Cherokee, find a cream puff, they are out there. I get around 20 from mine driving like I stole it. Between dependability, ease and cost of repair, total cost of ownership, I don't think you will find anything to beat these two choices. I purposi[ly left out Ford products after my experiance with the 4.6 in my Van. Teh Ford modular motors are a PIA to work on and are expensive to repair. On the Jeep, check around high end neighbor hoods, when the Jeep was new, they were the yuppie choice of vehicle, a lot of people kept them as back up cars while the Bimmer was in the shop, I see one every once in a while that loks brand new.

Good point Ferm. I was, of course, speaking about my Cherokee 4.0L which does have the distributor and coil, but you're absolutely right..the engine changed thru the years as progress marched on. As an example. my next door neighbor has a mid 80's(?) Jeep CJ(?) that's carburated, and of course, mine's injected. I'm sure that as you go thru the years there have been many changes to the engine, but whatever flavor it's in, it's still one of the best damn engines I've ever driven.

Not a fan of Surburans, because of their terrible (to me) turn radius, but I gotta agree with you Spare that they're reliable. I got 20.6 MPG on my trip to Fla. with my Cherokee. The Cherokees a tad small Charlie, but it turns on a dime, is reliable as sh_t and is in the price bracket you're looking in. Try and get one that has antilock brakes. Mine doesn't have them and I think* that Tsubaki said he had one and it had antilock brakes? Look for a late 90's vehicle as they are the more "stylish" with the smooth tailgate and sides... IMHO. Oh and make sure it's injected. You should be able to pick up a cherry one for about $4500. Less for a well used one. Given the area we live in, go under the tail of the vehicle and look at the frame rail where it crosses the rear axle. I've seen several rust in that one spot. Other than that they seem to be pretty good with road salt.

A 96-99 TAHOE or YUKON with the 5.7L VORTEC V8 would be at the top of the list. The turning radius was poor on the 95 and older ones, but 96+ are MUCH better. A 91-95 CHEROKEE would be at the top of the list as well. 96 is when CHRYSLER started implementing alot of there so called upgrades and the downward slide started. ALL of the grand cherokees with a 4.0L have sorry trannies in them, and the differentials in them have proven troublesome over the years in the 4X4's. The small BLAZER isn't bad, but the 4.3L V-6 leaves alot to be desired as far as power goes after you've driven something with a 4.0L in it. One of the new style(99-04) grand's with the 4.7L V-8 has a good engine(if it is maintained properly), the trans in them is solid and lasts, but you are still stuck with the crappy diffs that CHRYSLER put under em that like to sing like crazy. The EXPLORER isn't bad, but I'm just not a FORD fan. And there are some decent imports out there, but I don't drive rice.

i've had 3 of those motors and they are good for 175 to 200 K miles then the rear main seals leak you just drop the pan replace the main bearings and the seals then it will go another 200 K tough motors if you ever rebuild one you should always make a stroker out of it with just changing the crank and rods to a 4.2 older 258 jeep motor. the 4.0 / 242 is one good motor.

In my opinion the only candidate to fit the bill:
3rd generation Toyota 4Runner. 1996-2001
http://i1141.photobucket.com/albums/n581/thatkidjordy/IMG_0289.jpg
My wife drives a 2nd generation, but the 3rd gen has the much improved 3.4 liter engine.
4Runners have a cult like following:
