I bought my 1999 Jeep Grand Cherokee (6 cyl.) in 2011 with 162,000 miles on it to use as a work truck.
I'm a construction contractor and used this truck accordingly.
For the price I've paid it is the BEST money ever spent.
I've been told that the in line 6 cylinder engine is the only way to go in that it will last for 300,000 miles.
It is now at 200,000+ and runs great.
There is some slipping in the transmission into 3rd gear but it stops when the engine is warm.
I plan on driving it till it goes and will replace with another.
It is a great beat around truck for me and I love this vehicle and will likely by a 2013 Grand Cherokee with the latest body style etc...
