The 1991 Toyota 4Runner has earned a wonderful reputation as a solid, reliable SUV. The standard engine was a 2.0-liter I4, while buyers opted for a 3.0-liter V6 or either a 2.8- or 3.0-liter diesel V6.

While reviewers have praised the SUV's ruggedness and dependability, the complaints center on poor mileage (though many have said it is still good for an SUV) and weak engine. The V6 seemed to have been just enough to propel the growing SUV, while the I4 seemed to struggle under the weight.

For an older car, maintenance costs are few, and the exterior seems to be near-rust-free. Congrats to Toyota on building such a rugged SUV and to you if you own one!
