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
