Felders, spoke to my dealer today, my car is at port in UK with a transporter on its way to pick it up hopefully in time for Friday.
Dealer said couldnt pick it up Saturday due to the Focus release, however it did say if it wasnt Friday it would be Monday or Tuesday so I dont think you would have to wait until the 18th.
Your dealer should be able to tell you exactly where it is from the tracking system, i.e. has it left deport in cologne/flush, holland or is it actually in transit to the uk, i.e. at dock awaiting delivery to dealership.
Once at dealership it should take no more than 2 days (servicing, degreasing, taxing and all that stuff)
Cheers
