Somehow it just seems the sixes are generally simpler and last longer without overhaul. I'm not concerned with missing the v8 power as I have other v8 cars.
The total cost (parts & labor) of repairs to the present engine (M116 V8) is the most that could be spent (again, parts & labor) to replace with an M103 I6.
The "worth" of the car is not relevant to the comparison, unless, of course, you are in the trade; in which case your question would not arise.
