Don't normally post deals I am considering , as they might sell out , doubt it applies to cars though !
The 2017 spec Focus has everything you could want (including Sat Nav, parking sensors and cruise control, )
OK its due to be replaced next year, by a "new" (seems very similar) model , but a new car at 25% off cannot be sniffed at and will take care of a lot of the depreciation .
You could get a year old model from Motorpoint (other car supermarkets are available !) with 12000 on the clock (with a lesser spec ) for £12999 - but I'd prefer to pay the extra £2K for Sat Nav , reversing sensors ,Cruise control etc and a full 3 year warranty .
Haven't a clue what it would cost on PCP/PCH - wouldn't touch that method of buying with a very long bargepole but I know they do it .
