My guess is you have around a 1% chance of IMS failure this year. You can improve those chances somewhat by driving the car more often, warming it up and then driving it in auto-manual to 5Krpm+, etc. Nothing short of an IMSR would increase the odds on the IMS and there are 20+ other identified failure modes.

An IMSR on a TIP is probably $2-3k plus because the trans and the engine have to come out as a unit, then be separated. (The $1.8k above for a TIP is very low compared to other quotes I've seen.)

A used engine...anywhere from $4k to $30k depending...with just used and no labor being the low end, a completely rebuilt and much much more powerful engine installed at the high end.

Any car/make/brand could fail. Yours has been good. Why think it will be otherwise? Just drive it and enjoy.

(I'm in the same situation with a 58K '01S TIP and that is what I do. I try not to baby it too much and I take it out and enjoy it. If it breaks, I'll deal with it then. Until then, I'm enjoying it and not worrying a bit. Could it fail tomorrow? No..it's too cold for me to take it out of storage. But the first day it is warm enough....)
