Cheap to run early — then the bills accelerate
Some models age gently, then hit a wall. Mercedes-Benz SLK's failure rate climbs 7.8× faster once it passes year 7 — exactly the window a warranty is meant to cover.

Mercedes-Benz SLK failure acceleration
Each model's failure-by-age curve is checked for a real inflection point between ages 4 and 12 — an age after which failures accelerate. The multiple is how much steeper the curve gets past that age. A vehicle can look cheap on early-year data and still carry a steep later bill.
