How is the Deal Score calculated?

The AI estimates the vehicle's true market value for its year, condition and typical mileage, then scores your asking price against it — factoring reliability and projected ownership costs — into a 0-100 score and a BUY, NEGOTIATE or PASS verdict.

Can I analyze both new and used cars?

Yes. Enter any year, make, model and asking price, whether it's a new dealership listing or a used private-party car.

How accurate are the cost projections?

Estimates are AI-generated guidance built from typical maintenance schedules, depreciation patterns and regional cost averages. They inform your decision rather than replace a professional inspection.

Can I cancel my subscription anytime?

Yes — upgrade, downgrade or cancel in one click from your dashboard. Billing is prorated when you switch plans.

Dealer visit checklist

2021 Ford Mustang checklist

Print it or keep it on your phone. Tick each item as you go so nothing gets missed.

Inspect the car

Check every panel gap and look for mismatched paint (signs of past accident repair)
Look at the tires: even wear, matching brands, at least 4/32" tread
Check under the car and engine bay for oil, coolant or other leaks
Start the engine cold; listen for knocks, ticks or squeals and watch for smoke
Test every window, lock, seat, light, the A/C, heat and infotainment
Test drive on city streets and highway: straight braking, smooth shifts, no pulling
Ask for the service records and a vehicle history report
Have an independent mechanic do a pre-purchase inspection (about $100–$200)

Negotiate the price

Know the typical price: about $25,000 for this model year
Negotiate the out-the-door price, not the monthly payment
Get the full price with every fee listed in writing before you sign
Bring your own loan pre-approval so the dealer has a rate to beat
Say no to add-ons you didn't ask for (paint protection, VIN etching, nitrogen tires)
Negotiate your trade-in separately, after the car's price is agreed
Be ready to walk away; another listing is usually a click away
