Jim,
I guess your 1999 Boxster isn't worth very much in the US, but saying that, the car was an expensive item when new. At 30,000 miles you are driving a vehicle that is only just nicely run in, so with the correct maintenance regime in place, you could well be driving it for the next 100,000 miles.
You dont say how often the car has been serviced, how long its been stood idle or if it was garaged all its life - these things really have an impact on the condition of the electro-mechanical workings (read reliability) of the car.
Get the IMS replaced by a reputable shop, together with a new clutch and updated RMS. You then don't have to worry about that concern for the next 50,000 miles.

Next step is go through the car maintenance as per book (coolant, brake fluid, filters etc. Apart from engine oil & filter which really should be replaced every 5,000-7,500 miles regardless of what the Porsche maintenance schedule says.

Even without the IMS retrofit, budget the initial maintenance costs to be at least $1,000 if you do it all yourself or at least $2,000 if you pay someone to do it.
Then enjoy it........
