Jay,
You're still making me laugh....
Regarding your journey, make sure you use the M6 Toll, even on a Saturday afternoon/evening. It might cost £4 (or whatever) but its worth every penny and an excellent place to test the max speed of your car
Regarding washing your car, I wouldn't bother because once you've driven through a few "fords" your car will be covered in muck. Also be careful as some of them have fish in them...
Looking forward to meeting you
