We had a 98 Durango, and it was great! unfortunately there were some things I didnt like, and I think the new 4. 7 engine might be better.
What we didnt like.
We had every option including the full time 4X4 transfer case with the 318. That Durango was so underpowered, it couldnt get out of its way. It would get 12 MPG running 70 with a big headwind. In the Mountains it ran like a V6, and still got 13 MPG.
It would heat up in the summertime, as the radiator wasnt big enough for the 318 when it was 110 degrees outside with the AC on. You could see the temp rise, and the fan noise when locked up was annoying. We had the common problems that plagued the first year model, and most of those have been fixed.
We traded for an Excursion since it had a Diesel, gets 19 on the highway, and the Durango could fit inside the Excursion. We needed more room, and more power.
The Excursion fits my needs better, but the Durango is still a great vehicle.
FWIW, We have 10 1998 Durango's at work, and the guys have not torn them up yet. That is saying a lot!
