I am currently driving a nearly 15 yo 4WD pick up. It runs well, is low mileage for it's age (just under 100K), doesn't rattle, has no known mechanical issues, and will pull my boat or tractor with no problem. I recently looked at replacing it with a 2 yo low mileage truck, similarly equipped, and found that getting into a 2 year old updated truck, will cost me my truck & about $25-30K . I decided to drop about $3K in the old truck for some minor body work, aftermarket back up camera, & new rubber that I probably won't get back when I sell it. I am happy with this decision because I have always liked the old truck. As far as the economics go, I figure I'm way ahead driving it for another 3 or 4 years versus dropping that $25-30K, even though I prolly won't get my $$$ back when I sell it one day. QUESTION: When do you personally trade in an old car or truck that is in good shape, just to update it? Thanks. PS - I don't have a wife to satisfy with a new ride, just me.
