Chin up, Mate. It happens periodically, even with a warm place to work!
Before we got the Barracuda into shelter, it used to live on Gareths drive out in the elements and we suffered all the same problems, pretty much. Plus the joy of the kids from a couple of houses down scraping their handlebars down the side of it.
Don't worry about the carpets, that will only be on the surface. If you can get the windows down a bit to let the air circulate, or take it for a drive, that will help a bit, but a good brush over the surface and a hhover out will help too.
Can you use a car cover where you are, or is that not possible?
I bet I can guess every place the water is coming in, too.
That kit we spoke about for the wiper bushes is a cheap fix for the front end leak and a solid run at it on a Saturday or Sunday will see it done.
Best thing is to pump that tyre up and take it for a drive, that'll remind you why you love it so much and put a big grin on yer face!
Winters can easily get you like this... Keep yer pecker up and come on here as often as you can for help and advice, it'll keep you sane!
Good luck, Mate.
