The best replacement I have found is the Mercedes G500. It has the killer looks of a Gen I Montero, 3 lockers, solid axles, coil suspension, 300+ horsepower, 5 speed auto tranny with manual mode, and every amenity you could ever want. I have a 2003 and it has been a great vehicle. Their is no doubt in my mind that a 10 year old G500 is more reliable and will last longer than a new Rubicon. These G500's were made to go a million miles. and they are bullet proof, literally.
