What do you do if you drive a convertible and you park it but forget the roof down and it rains heavy outside while you are at your job?

If the door seals are good , it will fill up with a few tons of water that will break the suspension .

Put a trash bag in the seat and drive it like you stole it.

Drive home with a wet bum

Most people get the chance to run out and close the roof.  It can handle a washing on the inside. Some peoples kids- smh

You learn to be less willfully stupid in the future.

You allow it to dry of course. Maybe full sun in case it is not too hot. That might take care of the mold? Then you may want to have it checked by a professional to find out what is the damage because most convertible are not like farm tractors and are susceptible to water damage

You spend three days smacking yourself in your head.

You don't have that problem because you don't own one and can't afford one. TROLL.

You'll have to replace all the seats and all the carpeting. Probably some of the electronics too. Depending on how old the car is, it might be better to just junk it.

your seats will be ruined....consult a car repair guy
