I changed the coolant every 2 years religiously and my coolant crossover tube failed this summer at 251,000 km . So your comment that they will all fail is correct. The rubber seals on the end of the tube fails , not the tube. And the cost is about 3, 000 to replace it/
As for costs, this is an expensive vehicle . So accordingly you cost of maintenance will be higher. Whether the 4.8i is higher than the diesel I doubt. The engine just started to use some oil , and this week a DRL bulb failed. I now have to replace the valve cover gaskets. So the depreciation i was paying is now being replaced by repair costs. I followed the maintenance plan that is supplied by Mike Miller ( in Roundel). I would highly recommend transmission oil changes since I haven't had any problems with mine and the engine is still strong. I haven't really had any electrical gremlins other than the radio changes stations or turns on by itself ocassionally ( i had replaced the radio a few years ago.) . I am lothe to get rid of it because of the performance and features.

If you really want to know what the repair bills will be, send me a private note. I keep a spreasheet on all the repairs , etc So I have all the information in one xcel spreadsheet. Ill send it to you . You can decide for yourself.
