@gothitjulie, did you find the source of your problem with rainwater that gushes out when the driver’s door is opened?
No, it was just like yours though, you opened the door & the water came out onto your feet.
I’ve now got a different car & that so far doesn’t seem to leak, some bits have fallen off but being a Peugeot I’m sure they must add extra bits so that they can fall off to maintain their reputation.
