When will you sell your X5?

[carbob]

This is the different side of the coin from "how many miles do you have" and "what have you done for your X5" but I wanted to start some discussion (maybe another one) about how long to keep an old vehicle. Mine is now 20 years old, I love to drive it and it is dependable. It has been carefully maintained and is a 9/10 mechanically as well as exterior and interior, everything works as it should. I kept a spreadsheet since new and found that I spent $46,807 on maintenance and repairs since new excluding fuel, insurance and license. I has cost $191/mo over those 245 months at $0.44/mile. It seems like these past few years at least one expensive thing needed replaced but now I have a new front suspension, half shafts, brakes and rotors, valley pan gasket, alternator, and cooling system in addition to regular fluid and tire maintenance. Every time something big happens I wonder if I should have sold it sooner and wonder if I should fix it or dump it- sometimes the repair is almost what the value is. But now that the big stuff has been done, maybe I have some years left without high cost items, and maybe I should keep it, or maybe sell it because it is at its highest value. I wonder if others have thought about this and what they have used to help with the decision besides my gut and the cost of a new vehicle? There really is no feature on a new vehicle that I crave, although better gas mileage would be nice.
