Depending on what your after if you want something with a little "get up and go" the 4.0 inline six is the only
way to go. Other wise the 2.5 4cyl is the next best thing, utterly bomb proof, its just about as powerful as a pencil sharpener.
Things you want to check out. . .
Make sure its starts, runs, and drives.
Burns oil? how bad.
Loses coolant? how much.
Strange sounds? How loud how bad.
Clean title? why not.
Overpriced and Totally rusted/dented/wrecked beyond repair are about the only things that would drive me away from buying a comanche. Everything else can be readily fixed.
Also, pictures help immensely
