A low UK PCP monthly usually means a large optional final payment (GFV) is waiting at the end — not that the car is cheaper.
PCP amortises only the gap between price (minus deposit) and the balloon. Interest still accrues on the amortising slice; keep-or-return is a separate decision when the term ends.
Unless the car is worth more than the guaranteed future value at the end, in which case the balloon is a floor under your risk and the equity is genuinely yours. The GFV is a guarantee from the lender, so a market that holds up hands you the upside.
Estimate with the rule, then check it against the calculator that models it properly.
