Dv8, unfortunately there are no lift kits, locking differentials and other offroad options for Toyota Yaris. Old 2 door Chevrolet Tracker or Geo Tracker (rebadged Suzuki Sidekick) is the smallest and the most economical off-road SUV with the size similar to a compact car, but with real offroad capabilities and it can be tweaked if needed The only problem is to find one here in good condition. My wife had one here, but we sold it, too small for this country, not safe in case of accident.
