I almost 100% DIY. My tranny cracked a year ago. I dropped it off at the shop with a used tranny to swap out. That was cheaper than renting a car while I fixed it.
And my power window failed, same thing. I looked like a B@5t@rd of a job, so I dropped it off, only to find out the repair kit has everything all assembled and it's a piece of cake.
A year ago I bought all new suspension parts. They sit on the shelf uninstalled. No time.
And I did the head my five cylinder Volvo, I remember how pissed off I was that the bores were like new, I was hoping to scrap the car.
