Congratulations on the quick sale.
Be interesting to see what you buy once you are down here
How far from the sea front will you be? I lived one 'block' back form Burnham sea front for s time and the sand and salt used to blow up under the car and settle around the spark plugs.
(And everywhere else, but the plug holes required very careful cleaning!)
If you take a walk along the houses built behind the dunes, Trinity Rise etc, the cars look like they have been cleaned with a scouring pad.
