Floods

Lift the carpet in the footwells and look for any rubber bungs. If none, drill a hole in the floor pan. We had to do that with my old Triumph Spitfire.
Or use a pump to pump the water out and dry the rest out with towels, newspaper. Had to do that with the current car!

At home we would be able to do all of that with a wet/dry vacuum cleaner and power tools etc. Over here not so easy as it's inside a garage and to just get in the car I have to climb into the back seat and sqeeze through the front seats to get to the drivers position.  All in all its a perfect storm for being awkward.
