Trading a gas car for an EV: how to time it right

There's a persistent myth that the smart move is to drive your gas car into the ground, then go electric. Sometimes true — but for a lot of drivers, the math says the opposite, and the difference can be thousands of dollars.

Your gas car is a depreciating asset on a clock

Late-model gas cars still command strong money today, but the buyer pool for them shrinks every year as more households go electric. Meanwhile, used EV prices have stabilized after the wild swings of a few years ago — the depreciation cliff people feared has flattened into a normal curve.

Practically, that means the trade gap — what you get for yours versus what you pay for the EV — is often narrower right now than it will be in two or three years.

Run the real numbers, not vibes

Add up what you spend monthly on gas and oil changes, then compare it against home-charging costs — for most Portland commuters that's a $120–250 monthly swing on its own. Stack that against your trade value while it's strong, plus the point-of-sale tax credit on a qualifying used EV, and the 'wait it out' plan often costs more than switching.

Our online estimator gives you a real range for your car in about a minute — no phone number required, no follow-up calls. That number is the honest starting point for the whole decision.
