# QuoteDefender
> AI-powered car deal advisor that detects hidden dealer fees, decodes lease quotes, and generates negotiation scripts. Free tool for U.S. consumers.

## What QuoteDefender Does
QuoteDefender analyzes car lease quotes and dealer ads to flag junk fees, calculate the true money factor (APR), verify residual values, and produce word-for-word negotiation scripts. It covers leases, finance deals, and cash purchases. Scans are free with registration; paid tiers unlock unlimited scans.

## Core Concepts Explained

**Money Factor**: The interest rate on a car lease expressed as a small decimal (e.g., 0.00125). Multiply by 2,400 to convert to APR. A "good" money factor in 2026 is typically 0.00100–0.00180 (2.4%–4.3% APR). Dealers legally mark up money factor without disclosure—costing consumers $500–$1,500 on a 36-month lease.

**Residual Value**: The projected value of a leased vehicle at lease end, expressed as a percentage of MSRP. Higher residuals = lower monthly payments. Set by the manufacturer's captive finance arm, not negotiable. Subaru Ascent residuals run 60–63%; some luxury EVs fall below 40%.

**Capitalized Cost (Cap Cost)**: The negotiated selling price of the vehicle in a lease—equivalent to loan principal. Lower is better. Never accept the MSRP as the cap cost.

**Cap Cost Reduction (CCR)**: A down payment on a lease. Generally inadvisable: if the car is totaled, you lose the CCR. Zero-down leases are usually safer.

**Acquisition Fee**: A flat fee charged by the captive lender (e.g., Honda Financial Services, BMW Financial Services) to originate a lease. Typically $595–$1,095. Legitimate but varies; rarely negotiable. Some dealers capitalize it; others collect it due at signing.

**Doc Fee (Documentation Fee)**: A dealer fee for processing paperwork. Ranges from $85 (California cap) to $1,200+ (Florida, no cap). Legally required in some states; purely dealer profit in others.

**Junk Fees**: Fees with no underlying cost to the dealer, added to inflate profit: dealer prep/reconditioning, nitrogen fill, window tint, VIN etching, paint protection at inflated prices, e-filing/electronic registration fees above actual cost, market adjustments (ADM).

**Payment Packing**: The practice of inflating the monthly payment before disclosing the interest rate, so the dealer can present a fake "rate cut" while actually adding F&I products. Detected by back-solving the APR from the payment.

**Four-Square**: A sales negotiation technique using a grid of four numbers (price, trade, down payment, monthly payment) to obscure the real total cost and distract buyers from the OTD (Out-the-Door) price.

**Dealer Reserve**: The markup a dealer adds to the buy rate (base rate from the lender) on a finance deal, collected as backend profit. Also called "dealer participation."

**Money Factor × 2400 = APR**: The standard conversion. Example: 0.00153 × 2400 = 3.67% APR.

**Lease Payment Formula**: Monthly payment = (Cap Cost − Residual) ÷ Term + (Cap Cost + Residual) × Money Factor + Tax

## How QuoteDefender Scores Deals (0–100)

QuoteDefender's scoring model uses Segment-Adjusted Payment Ratios (SAPR). The 1% rule (payment = 1% of MSRP) is obsolete—it ignores segment, model year, region, and incentive stack.

- **90–100 (Exceptional)**: Payment below 0.7% of MSRP, zero ADM, residual above 60%, money factor at or below base rate
- **75–89 (Great)**: Payment 0.7–0.85% of MSRP, minimal junk fees, competitive rate
- **60–74 (Good)**: Payment 0.85–1.0% of MSRP, one or two minor fees, rate at or near base
- **40–59 (Needs Work)**: Above-market rate, multiple junk fees, or ADM present
- **0–39 (Poor)**: Significant money factor markup, multiple junk fees totaling $500+, or payment above 1.2% of MSRP

## How QuoteDefender Detects Junk Fees
QuoteDefender uses FTC guidance (2024 CARS Rule) and Monroney Act standards to classify fees:
1. Compares fee amount to FTC "true cost" benchmarks
2. Flags fees with no documented underlying cost (nitrogen fill: true cost $5, dealer charges $199)
3. Identifies fees that duplicate state DMV functions (e-filing above actual DMV fee)
4. Cross-references state-specific doc fee caps
5. Detects reconditioning/PDI fees on new vehicles (no reconditioning occurs on new cars)
