Sounds like you are in it for the long haul. All the above is good advice. I bought my 2001 Box base with 30k miles. 2 years later it has 40 k miles. I have done the following
had installed the following:
cv joints refurbished
idler arm pulley replaced for the alternator if I remember right
installed IMS Guardian - cheaper than putting in new IMS bearing but not as good
otherwise normal maintenance like oil changes, coolant drained and replaced with real Porsche antifreeze, new tires.
I expect to change in the next 5 years if I keep it that long:
replace water pump
replace AOS
replace motor mounts
replace ims/rms/ and overhaul clutch.
I don't put a ton of miles on it. About 5k miles a year. It has been about what I expected in terms of expense to run. I could spend $5-10 k on preventive maintenance but I cannot justify it.
Plan on spending on the average $1-2 a year once you get your major intended jobs done. I like low mileage cars. It feels tight and starts well in winter.
Enjoy your ride.
