What it shows you

Not just the sticker price. What it actually costs you every month to own.

Full monthly cost breakdown

Loan payment, insurance, fuel, maintenance, depreciation, and taxes/fees — all in one number, not scattered across a dozen tabs.

Good Deal / Priced High indicator

Compares the asking price against real depreciation data for that model, so you know if it's actually a good price — not just a guess.

Hidden cost warnings

Flags vehicles with unusually high maintenance, insurance, or depreciation before you find out the hard way.

Similar vehicles, lower cost to own

When there's a genuinely comparable model that holds its value better, it'll tell you — based on real published data, not guesswork.

History & side-by-side compare

Every vehicle you've looked up is saved locally, so you can pull up two and compare them directly.

Your budget, respected

Tell it your monthly budget and it'll flag clearly — not buried in fine print — when a car runs meaningfully over it.
