I was wondering for those that own an Apache/Geronimo how much on average does the annual cost. My research has told me that the first will be an expensive sorting out exercise, and I should factor in as much as 25 percent of the purchase price for this. I'm fine with this. Once the big stuff is taken care of and it's down to maintenance how much are most spending? I realise this is a 50 plus-year-old so regular maintenance is somewhat subjective. Just curious.
