There are few vehicles around that can take the kind of punishment a Jeep can and ask for more afterwards. Yes you will have to maintain it yes it will have drips and leaks and other gremlins but parts are plentiful and cheap. Personally I'd look for a 1st Gen Grand Cherokee with the straight 6. They go for $1k to $5k up here and will go almost anywhere a wrangler will. Also solves your passenger problem.
