Basel parking

Does anyone know any parking/showers in the Basel area?

There was an autohof on the German side which I stayed at but it was almost 20 years ago now, Weil am Rhein, or something like that.

Ok, I thought I could of parked Muttenz where all agents use to be but I don’t think it’s used anymore. I decided to book into hotel as I’m here till Wednesday and its 30 degrees. Thanks Andy.
