Hi Leo
You may be able to translate using Google Translate, as I am not fluent in Spanish.
I had a 1999 Jeep Grand Cherokee which was the first year of the WJ model. 2004 was the final year. In the US, these had a 4.0 liter, straight 6 cylinder engine, so I can not speak to the 2.7.
I can say that in all other ways I liked the platform. There was "enough" room, though not copious amounts. Interestingly, when compared to the 2019-2024 Subaru Forester, the outside dimensions and the interior space is nearly identical.
Coil springs made installing a modest lift easy enough. The coil spring perches have rubber isolators which are replaceable. You may want to do that as it offers a refined ride both on and off road. I had replaced my coils with 2 inch higher Iron Rock Offroad springs, new perch isolators and Moog anti sway bar links. I installed a new drag link and a completely new tie rod and pro comp 9000 series shocks. Then I put on wheels and tires from a Wrangler and the vehicle behaved wonderfully both on pavement and on dirt roads, camo roads, easy trails, and fire service type roads.
There is an A-shaped rear upper control arm that is unconventional and a common failure point, so be watching for that.
The spare tire well: some people think it hangs too low under the vehicle. Depends what type of offloading you will be doing and how much you lift the vehicle. I never really had a problem with it but I really did more "SOFT-roading" to camos and kayak put-in areas.
Keep in mind, the rear skid plate is directly supporting the gas / fuel tank. Make sure to grab a spare one of those if you can. They definitely tend to rust in the New England USA area, not sure about where you are.
I wish I still had 1999 Jeep Grand Cherokee, but I could not keep too many vehicles where I lived at the time. Now I I bought a house where I have room for it, but it is already gone.
Best of luck. I'll be watching this thread
