I've previously owned the Jeep Grand Cherokee and have recently bought a 2003 Wrangler. I love the Jeep reputation and reliability!!
I just did have to have my vehicle worked on as 2 of the 6 spark plugs fouled at the same time. Not sure why they didn't replace all 6, but from reading different material, seems my son (he's 32) will be able to replace the other 4.
