General Comments:

I have owned several SUVs, and I worked for several years as a mechanic, so I know my way around a vehicle.

The Cherokee I purchased was not taken care of as it should have been, but since it was only $400, I bought it. You will see the list of problems/repairs I have done and think I bought a lemon, when in reality most older SUVs will have a lot of issues when you buy them for under 1,000. I have owned several SUVs (1995 5 speed 3.0 4x4 and 1997 5 speed 3.4 4x4, a Pathfinder 3.0 5 speed 4x4, 1993 Suburban, 1993 Explorer 4.0 4x4, 1999 Blazer 4x4).

Where most SUVs fall short is their MPG and towing capacity. The Suburban was great, but had poor MPG and poor off road capabilities due to its weight. The 4Runner was excellent off road, but had horrible MPG. The Pathfinder was great off road and great MPG, but poor towing. The Cherokee is the only one that can give me 20 MPG highway, tow a car on a tow dolly (4,000lbs) easily, and is excellent off road. That is a lot to ask for out of a SUV. If I baby my Cherokee, I can get even better than 20 on the highway; my 3.4 4Runner struggled to get 16.

Next there is the replacement parts, which most Cherokees need a lot of love, but don't worry, it's so cheap if you do it yourself. I did my entire cooling system for $240 including the coolant! The fuel pump is easy and only $115. If you can't repair your Cherokee or have someone that doesn't mind doing it for cheap, I would not recommend them if you plan on taking it to the shop for everything; you're better off buying a new vehicle, because old vehicles need boat loads of money if you're paying people to keep them going.

I can't believe the American perspective on fuel economy!

Wow, 20 MPG! You obviously think that's really good! These Cherokee's were sold in the UK with a 2.5 turbo diesel that in the real world had as much in gear torque as the 4.0 petrol, but crucially, will do 30 MPG, yes... 30.

Imagine how much money you could save if Americans embraced diesels, with the fuel prices you luckily have over there. And, most modern diesels are as nice to drive, or nicer, than their petrol equivalents, because they have way more low down torque, and are virtually as refined these days.

I wouldn't have a diesel if it was given to me.

I am an American living nearly 20 years in India, and understand the obsession with fuel economy in much of the world - we're paying the equivalent of $5.50/gal here, and have a 2001 diesel 5-dr Jeep that even being old-school non-electronic, non-turbo does 25-30mpg. It's slow and noisy, but indeed, more modern diesels are great. Still, I drove that old 4.0 back in the day - it was a real gem of an engine. A side-by-side road test against the 2.5td would have been highly interesting. I'm sure that performance-wise the 4.0 would have excelled in every area. Plus quieter, less polluting, and easier to start in the cold.

1991 Jeep Cherokee Laredo 4.0L I-6

Summary:

I love Jeeps!

Faults:

This Jeep is amazing. It is my third Jeep; all three have had the 4.0L I-6 and 4x4. They have all been extremely reliable. They aren't the best of MPG's, but I don't really care, I love my Jeeps.

General Comments:

I have had 3 Jeeps, they have all been great. I got my recent one just a few days ago; it's 20 years old and only has 109,000 miles, and is completely perfect, inside and out.

All three of my Jeeps have had the same 4.0L motor and 4x4. I have had no major trouble with any of them, and I am so glad to have another. It really is a Jeep thing, and no one would understand. I think it's either you love them, or don't like them. They have their own ways; they sound different and drive different than anything else. I love them, and plan to always have one.

It has plenty of power, I like the rugged looks, I like the go anywhere nature, I like the way that even though it's 20 years old, it still has a classic iconic look that started the SUV craze.
