Arnold makes some interesting and relevant points. Certainly I would have agreed with him 100% before my last PCP experience:
Golf GTD (DSG) with about 3k of options on it (Pro-nav, Dynaudio, Winter pack , camera etc)
Bought through drive the deal for 26k (13% disc) and financed over three years
Sold after two years for 17,750 (the car was virtually as new apart from tire wear). At that point the finance settlement figure was 19,250 so I had to pay 1,500 to get rid.
Now had I kept the car for the full three years the final payment would have been 16,041. Would I have got that in a private sale - maybe, but not sure I would.
