Sure, I can give you some general winter tips:
DO NOT use the handbrake if it can be avoided. One day last year when it was 15-20 below, I parked my car with the handbrake, drove off (if it's snowy you don't really notice that the rear wheels are locked at low speed) and on the first turn out on the main road the car went spinning... ). Not a very good situation. You can "unlock" the handbrake usually by placing a pot of boiling water or something under the car where the handbrake mechanism is (not a lot of fun though when you're supposed to be on your way to work or wherever...)
2) Dooor Locks
Remote controlled central locking really comes in handy, but if you don't have a remote, you should just rinse and then oil the lock well, perferrably before the temp drops below zero, this should keep the lock free from water so it can't freeze when it gets cold. I also keep a small spray can of that stuff you use to defrost it (smart to keep this somewhere else than inside the car!!) if it should freeze anyway. Remember though to oil the lock again if you have to use this, because it removes the oil in addition to removing the ice...
I always go over all the rubber (like the ones in door/window sills) on the car with a silicone stick before the winter kicks in, to avoid doors and windows from freezing, etc. Use a stick, not spray, the stick is much cheaper, lasts for years, and the spray usually goes all over the place, not only on the rubber...
I usually polish and then use a paint sealer (teflon hard wax) on the car just before winter kicks in, and then when I wash it during the winter I try to wash it only by using a hose, no sponge or anything (doesn't get that clean, but the polish stays on longer), then when spring comes I do a proper cleanup. You could also do this once during winter I guess if you think the polish/wax layer is starting to wear off.
5) Window washers etc.
I usually change mine at least twice a year (a bit expensive, but much cheaper than changing yuor window because you get those little stripes from worn blades on it...) I use pure window washing liquid in the winter, don't mix any water in it if it could get very cold. When the liquid is without extra added water I think it can handle down to 40 degrees below. As for frozen window washers, I don't think there is any other trick than letting the car warm opp and defrost the window, and always remove snow and ice manually before starting the wipers to avoid damaging the washer engine...
That's about it I guess, questions and comments appreciated! Hope it helps you during these horrible months when at least I wish I lived in the country Alfas come from... [img]smilies/biggrin.gif[/img]
