Prompt
You’re reviewing a US retail installment sale contract for a car purchase. Pull out the APR, amount financed, finance charge, total of payments, term, and monthly payment. Then list every add-on — extended warranty, GAP, service contracts, dealer fees — with the price of each. For each one, tell me whether the price is typical, whether it’s optional, and what I should have asked. Flag anything that looks unusual.
However — understanding your contract with real benchmarking, compared against thousands of existing real contracts and real market data, with every benchmark cited, is a different thing. When you’re spending $20,000 or more, that’s worth being sure about.
