I've got a brand new Ram. It has twice the horsepower, gets twice the gas mileage, and is twice as quiet as my Disco. Which one would I drive across the country on a trip I wanted to enjoy, and have memorable experiences on? The Disco, without a moment's thought. Your choice of vehicle is half the fun of any road trip, and I can't imagine a cooler car to drive across the country in (that's a lie...C7 Vette probably trumps it). It's such an iconic vehicle, and it reeks of "adventure" when you see it, even if you don't plan on leaving the pavement. It makes you want to drive it, just because. As for maintenance? I've done all my own work, torn the motor down to the block, and put it back together again. Not only do I trust my work, and therefore my truck, but in the unlikely event of a breakdown I would frankly relish the opportunity to fix it again because it's so easy to wrench on.
Drive the Disco, make some memories.
I don't know how old some of you are but i for one don't consider driving through a remote wilderness with your family in a old unreliable Land Rover an " adventure". I had my fair share of adventure many years ago.
The Aluminum Land Rover V8 engine is a piece of SHIT ! no matter how many times you strip it down.
You can't polish a turd.
