Some suggested meanings to car names...

but I am using just two examples...

BMW


Brings Me Women

to me, it is more like Big Maintenance Worries.

FIAT


Failure in Italian Automotive Technology

This happens to remind me of an old TV advertisement in UK, which if my memory serves me well goes... "designed by Italians... built by robots..." and some jokers altered it to '... and driven by British' showing an accident scene.

Then, there was a joke about Italians (because of their role during the Second World War) building cars with one forward gear and four reverse!
