If you speak French to Mistral, it gets it right everytime: Je veux laver ma voiture. La station de lavage est à 50 mètres. J'y vais à pied ou en voiture ?

I've been gone from France too long. I've never heard "station de lavage" before.

Very awkward and formal. Anyone would call it lavage auto, lave-auto or simply lavage if the context is clear.
