Renault used to have a 46% stake in AMC back in the '80s but sold it to Chrysler and hasn’t been back since.

The only French automaker in the US is Bugatti, and it’s questionable how French they are.

I’m hoping the Stellantis merger leads to more French cars here. Peugeot, Renault, Alpine, Citroen, and DS all have cars I’d be interested in.

I don’t know if there are zero Renault in the US but Mozilla themselves say that Renault aren’t sold in the US:

While Renault cars haven’t been sold in the US since 1992, their cars are big in Europe, South and Central America.

So it is kind of strange to hold it against them. On the other hand that doesn’t seem to be too important because nobody cares about what they signed or not.
