A simple A–F grade — like school, but for your car deal
Know What You're Walking Into
Quick reads on the most common things dealers do — so you know what to expect.
Compare Written Financing Offers
A dealer-arranged offer may differ from a direct lender offer. Ask for the written APR, lender, term, and amount financed, then compare complete offers before deciding.
Get Every Fee Itemized
Taxes, title, registration, dealer fees, and optional products serve different purposes. Ask what each charge covers; whether it is required or negotiable depends on the written terms and local rules.
Review Optional Products
The finance office may offer service contracts, protection plans, or insurance. Ask for the itemized price, coverage, cancellation terms, and whether you want each product before signing.
Handle One Number at a Time
Dealers like to mix your price, trade-in, and monthly payment together. Focus on the vehicle price first. Then talk financing. Then trade-in. Keeping them separate makes it easier to spot a bad deal.

Disclaimer
TheiaScan is a coaching tool for car buyers. Everything it shows — scores, grades, and tips — is for general guidance only. It is not legal or financial advice, and we are not a lender, attorney, or financial advisor. Always review your contract carefully and consult a professional before signing.
Results are based on the numbers you enter and publicly available market data. Deal rates, fees, and promotions vary significantly by region, timing, credit tier, and individual lender. This analysis is a mathematical reconstruction and not a guarantee of any specific outcome or approval. Individual dealer offers may differ materially from our model's estimates.
TheiaScan uses deterministic calculations for the score and de-identified records for limited benchmark calibration. Market conditions change frequently, so national averages are context rather than real-time quotes, approvals, or predictions for a specific dealer.
