I have a set of intact manifolds with pre-cats that I could give you. That would solve the precats problem, but we'll forget it because with 165,000 miles, there are likely a few more issues coming your way just from sheer age...
Tranny synchros, hoses, axels, water pump (likely soon), radiator (as it is running hot), suspension bits...etc. Time to move on & perhaps have the 'Tour as a second car and get parts from the bone yard as needed.
If the '05 Focus is a stretch, have you considered something a few years old? You might be able to get into one for half the price - although the financing costs may be higher, that would save you some monthly $.
