As an old Jeep driver i`ll tell you why i am driving one. In my off road experience i witnessed some wild situations. I know our marshals will say i am making people afraid but thats my experience. There is good chance while dune bashing you may flip your car, you may hit another car, you may fly over the dune with your car. I even saw while trying to tow other car you may brake your car`s chassis. All of these things are what i experienced over last few years. I personally flied over a dune and smashed the front of my Jeep. In such case my car is worth nothing to me, when you compare the car value over my income it is nothing. Today if i total my Jeep tomorrow i will go buy another one, simple.
Think like this how would you feel if someone T boned your Patrol while off roading or how would you feel if you fly over a dune a smash the from end. There you will find your answer. People might say old cars need lots of maintenance, indeed they need lots of maintenance. Also when you calculate the depreciation of new car will cost more than a maintaining an old car. Basically my Jeep wont lose more value than it already lost.
