Frequently asked questions

Is it ever cheaper to keep an old car?

Often, yes. Once a car has done its biggest depreciation drops, the cost of keeping it on the road — even with the odd repair — is usually lower than taking on a new finance deal and a fresh depreciation cliff.

What's the 'forecourt cliff'?

It's the chunk of value a replacement car loses the moment you drive it off the forecourt — typically around 20% in year one. Showroom finance quotes rarely highlight it.

How accurate are the figures?

v1 uses UK-average running costs and a placeholder DVSA-style repair curve. They give a solid directional answer; we'll swap in real TrueCarCosts data as it lands.
