It's just the way it was done.
There is no electrical advantage or disadvantage one way or the other. Both ways work equally well.

There are the theorys of electron flow vs current flow, but in practical application it makes no difference.

As was well put below, it's just the way the engineers did it. I think GM was one of the early ones to go negative ground and Chrysler was one of the last.

I've asked old-timers who worked on electronics of the '40's & '50's why the change? Mostly no one is sure, but it may have been that GM was negative ground and in those days GM was something like 60% of the automotive industry. Electrical accesories were becoming more common, so designers went with what the biggest force in the industry had. The rest just followed suit.
But, remember that is just a theory too.
