The dealer quotes you $399 a month. Here's what the car actually costs.

Thirty seconds, no sign-up, no sales pitch.

Every clip is the real page, recorded from the app in a headless browser. Pick a state and watch the drive-off prices move, switch from cars to bikes to boats to aircraft and watch every filter change with them, or open a card on a phone and drag the trim slider.

Your state, every price

Pick a state. Every price moves.

California, Texas, Oregon: the sticker stays, the drive-off number changes with sales tax, doc fee and plates. Then two taps narrow 414 cars to hybrid SUVs.

Cars · bikes · boats · aircraft

Four kinds of vehicle, one page.

Switch to motorcycles and the filters become engine size and transmission; to boats and they become length, propulsion and fuel burn per hour; to aircraft and they become seats, engines, range in nautical miles and fuel burn. Photos, prices and fees follow.

On your phone

Built for the dealership parking lot.

Tap a card for the breakdown from sticker to drive-off, drag the trim slider, scroll the fee lines, then set a budget in the filter sheet. 44 px targets, one hand.

“What's your monthly budget?” is the oldest trick on the lot.

It works because you don't know the drive-off number. You can't hold a $42,000 sticker and a $399 payment in your head at the same time, so you negotiate against yourself. CarFinder breaks the trick by putting all three prices on every card.

• ListThe maker's price, from the base trim to the top one, with the mandatory destination charge underneath.
• DealerThe band dealers really sell that model in this month: at sticker, a little under, or deep discounts.
• Drive-offThe estimated total once your state's tax, title, doc fee and registration are added. The number that leaves your account.

Now you walk in knowing the number. Bargain inside it. Never accept above it.

Pick your state. Watch every price move.

Choose a US state, an Indian state, a Chinese city, an Australian state, a Mexican estado, a Spanish region, a Russian region, a Brazilian state or a Canadian province, and every drive-off price on the page recomputes with its sales tax, road tax, plates, registration, insurance and rebates. Nothing to install, nothing to sign up for.

1. Pick cars, motorcycles, boats or aircraft, then your country

   The four buttons at the very top switch the kind of vehicle; the country tabs under them switch the whole page: the vehicles, the price basis (MSRP, ex-showroom, OTR, 指导价, RRP, ride-away…), the tax rules and the glossary. World pools every country in one list.

2. Pick your state or city

   The picker under the search bar (next to it on a desktop) sets the taxes and fees. Every drive-off price recomputes for it, and the page remembers your choice in your own browser.

3. Narrow it down

   Tap the body-type and fuel chips, or open Filters for price range, size, brand tier, seats, drivetrain, minimum MPG and minimum electric range. For bikes the filters become engine size and transmission; for boats, length, capacity, propulsion and fuel burn; for aircraft, seats, engines, minimum range and fuel burn per hour. Or press Help me choose and answer four questions.

4. Sort by what matters to you

   Price, lowest yearly fuel cost, best MPG, longest electric range, most horsepower, cheapest per horsepower, most seats. On a phone the sort lives behind the ⇅ button next to the search box.

5. Open a card, then compare

   Tap any card for its photo, the cost breakdown and the trim slider from base to top trim. Tap + Compare on up to four cards and see them side by side.

The same car, eleven prices.

Each tab starts from the price that country actually publishes and adds what that country actually charges. The rules were researched market by market and are written down in the repository.

Not only cars. Bikes, boats and aircraft, same rules.

Switch the page to motorcycles, boats or aircraft and nothing is a car in disguise: the price basis, the fees, the filters, the wizard questions and the glossary are the ones that market actually uses for that kind of vehicle.

Sit down already holding the dealer's playbook.

Every card answers the questions the salesperson would rather you didn't ask: is this model selling at sticker or sitting on the lot, which fees are real, and which ones you can push back on.

01Is this car hot or sitting?

The market badge says it plainly. Red: sells at or above sticker, expect a wait. Grey-blue: small discounts are typical. Green: big discounts and incentives; this is where the deals are.

02What should I actually pay?

The drive-off range starts from the sticker, applies the typical dealer discount or markup for that model, then adds your state's tax, a typical doc fee and registration. Bargain within it; don't accept above it.

03Which lines can I negotiate?

Open a car and drag the trim slider from base to fully loaded. The breakdown updates line by line: destination, discount, tax, doc fee, registration, insurance, grants, each with a note on what it is and whether you can negotiate it.

04What do I say to the dealer?

The Why this price band panel explains the market for that model and what to ask the dealer.

05What does it cost after I drive off?

Yearly fuel or charging cost at your local prices and distance, an estimated monthly payment, and the assumptions behind them, all editable. You set the term, not the dealer.
