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.
