After all, all car manufacturers use crimped connectors and 99.9% of the time they don't cause any issues.

crimp only if you have the correct crimp tool as well, if your gunna use some chinese pliers or something, better off to solder.

No, I'm not a salesman . I'm speaking from my personal experiences as a sparkie. Anywhere where movement occurs and solder is used is prone to breaking. Wire to wire solders joins seem to be ok (stresses not concentrated in one spot?) but wire joins to a fixed object are a no no in my book. Some original photos have not been recovered yet.
