At a crossroads with my car

[kk2002s]

Same crossroad different reasons
Car runs great. Just did 2200 mile trip no issues with 70k miles on her.
I have done services and a few replacements (DIY)
It was my daily but since January I commute by Train so car sits in the garage
I have gone back and forth on front suspension re-fresh.
I decided to go ahead (Have parts in hand Tie rods, Lower controls, drop links, sway bushings). I'm also doing Plug tubes, just put the car on stands last night

I also have a new AOS still in the box to put on. I'd like to do WP, low temp Thermo, tank and flush as that makes sense at 70k miles

Oh by the way I need new tires

I have 2 years left on loan and it basically gets used once a week. It's getting hard to get buy in from my financial adviser, My wife
Oh and Her new car also sits in the garage. I bought my daughter's 2003 jeep liberty 128k miles for most running around. Runs great

My only justification, besides keeping the car dependable, is it may be easier to sell
