I got my car back yesterday, and everything seemed fine, but I ran into some issues. I posted them over at Troubleshooting. I don't wanna go without my car anymore, it's not fun. If I can figure out what's going on with the AC and the coolant, I should be good for a long cruise now. I really don't want to push it until I get the coolant thing fixed, though. The whole wiring harness thing was pretty painless, and it seems the mechanic did a pretty good job, other than those problems. oh well.
