What the payment leaves out

  • Sales tax and fees on the purchase.
  • Faster depreciation on a newer car in its first years.
  • Changes in insurance, fuel or charging and upkeep.
  • The equity you give up — or carry forward — on your current car.

Three questions, answered separately

What does it cost? — Financial Tradeoff

The 36-month difference in cash spent and ending equity between keeping and upgrading.

How much better is it? — Upgrade Score

A 0–100 measure of the step up in age, mileage, reliability, running cost and vehicle features. A large price increase for a small step up is worth knowing about.

Is it right for you? — Your Fit

How the replacement lines up with the priorities you pick, such as reliability, performance or space, and whether you lean toward value or want.

The Carvest Recommendation weighs all three. A costly upgrade can still be the right call when the step up is large and fits what you care about; a cheap one can be the wrong call when it barely improves anything.

Run it with your own numbers
