Update on my vehicle/home trouble. I had to drop $400 for the registration this month, and the check engine light is still on due to a glow plug needing to be replaced. The CHEAPEST estimate I've found for the labor is $350+tax, and that's with me already having the replacement part and no guarantee of that actually being the final price. Any mechanic in this area who will work on an older diesel vehicle wants you to sign a paper that says you are paying for a repair ATTEMPT.
Glow plug replacement is a process notorious for "whoops I fucked it up and now need thousands in repairs" types of problems, so most mechanics won't touch it.
As a reminder for perspective: I live on $900/month in one of the most expensive locations in the country.
