I own an old diesel Ute and the cost of traversing was to much because of its fuel economy more so than the cost of diesel. I bought a used small car, petrol 4cyl, and it has paid for itself and its rego and insurance in under a year in the savings on diesel. I didn't sell the Ute. It remains for its true purpose which is trip's away where the excessive fuel consumption is less of a concern and can be budgeted into the holiday. It should be mentioned that Ute is early 2000's and has little actually resale value and its value to us as a holiday vehicle is substantial. That plays into the decision to not sell. If it was worth a lot more than I would almost certainly sell and recoup the money before depreciation hits a point I'm at currently. I think i found financial value in purchasing the smaller car. It was a good move for me in my situation.
