Well, all I can say is.........Jeeps have been around since 1941, and served in several wars. They're tough little vehicles, and you can do a lot with them. You just have to remember that they're not tanks, and you can't push them beyond what they're able to do. They handle different than cars, and even pickups. They're damned good in mud and snow. ( Especially snow! ) They're still relatively easy to work on, compared to what's out there nowadays.
As one member stated, the 4-bangers are a tad under powered, but if you down shift and keep up your revs, it'll be just fine. Keep 'em tuned up, put decent tires on them, and drive them with some skill, and you're gonna be hooked on them just like the rest of us.
I've had three Jeeps, my latest an '06 Rubicon.
Welcome to the Jeep world!
