Other than the AC tasks you have on your list, I too needed to do all of those tasks since I got my bird. And each task has been challenging and rewarding. Some tasks and projects took a day or two, others took months.
I know and feel your resistance to taking on big car jobs on the bird, but I want to push you in another direction:
YOU, yes you, can do these tasks and projects!!!
- Do one thing at a time if possible - Order the parts for one job at a time - Tell us all what you are attempting to do so we can assist - Realize some things take time, and some things are easy
Nobody here will steer you wrong (no pun intended). We can all help you through those tasks you listed. I can't help with AC but plenty of folks here can.
If the bird is in your home and under your control, then we can help. Once you pass the car over to someone else then we can only hope for the best. I've never handed my bird over to anyone or any business. They come to my house and do the work, or I do it myself.
