If you're worried about depreciation buy on a pcp with a guaranteed future value! When it comes to the end of the agreement and the value is lower than than the gfv you can still use your future custom to get a decent discount or dealer contribution towards your next car!
Don't want to upset or have anyone mislead , but you still stuffer the same levels of depreciation for that make and model, just it's been worked out before hand.
The monthly payments and GFV will alter depending on the expected value of the car at the end of the contract, they are very good at working this out and will penalise you if you break your end of the contract or return it overly damaged or with too many miles above the agreement which has caused it to depreciate further than agreed.
Choose a high depreciating make/model and the GFV will be lower so the monthly payments/deposit will be higher than a low depreciating make/model.
So, lets say two different make and models cost the same.
One has 70% depreciation, the other 50%.
The first car's GFV is only 30% of the total, so the buyer will need to pay the 70% (plus interest) by deposit and monthly payments.
The second car's GFV is 50% of the total, so the buyer will need to pay just 50% (plus interest) by deposit and monthly payments.
PCP's are actually better value when taken out low depreciating models, but they usually know this and therefore charge more interest.
To complicate matters more, the GFV comes into play again if you buy the car from the finance company, that is all you pay.
Or you can hand the car back to the finance company at the end of the contract and pay nothing more (apart from a collection fee).
Though it must meet the various conditions in the contract, like mileage, service history and condition (usually based on BVRLA fair wear and tear conditions) otherwise they will bill you for it.
You can return to the dealer (any dealer) and try part exchanging, but they aren't legally obliged when it comes to the GFV.
The GFV is between you and the finance company, not the supplier (dealer).
They may offer you less which will mean you need to finance the outstanding or, if they feel the car/you are worth it, the may offer you a bit more so you can use it towards a deposit on your new deal.
Overall, they tend to do the latter, but there's usually a catch, like only if you buy a much more expensive car, a deal on a higher finance rate or a model they have trouble shifting, otherwise there's little in it either way.
