How do I get a fair deal on a car?

Car buying, from the other side of the desk

Short answer: Know the out-the-door price and your own loan rate before you talk payments: the average 60-month new-car loan at banks was 7.54% APR in August 2026 (Federal Reserve G.19), and Americans owed $1.71 trillion in auto loans in 2026Q2 (New York Fed).

Why trust this: VaultRubric's owner spent 11 years in dealership sales and management. This guide explains how the deal is built from the other side of the desk, and every number is either cited or yours.

Short answer: walk in knowing your out-the-door price, your loan rate and your trade's value, and you take away the dealer's biggest advantages.

Best pick for your situation

Your first move: get a written out-the-door price and a credit-union loan approval before you visit a dealer. Those two numbers decide most of what you'll pay.

The math:

Example, Tennessee: $30,000 car + $699 doc fee + $2,237 sales tax (7% state tax on price + doc fee, 2.75% local tax on the first $1,600 at the most common county rate, and the 2.75% state single-article tax) = $32,936 before title/registration (run your state · Tennessee county examples).
A 1.25-point dealer rate markup on $30,000 for 60 months adds about $1,063 in interest (CFPB orders capped markups at that level).

Sources: FTC: Financing or leasing a car; CFPB: Take control of your auto loan (step-by-step guide); CFPB: Fifth Third order (dealer markup up to 2.5%, capped at 1.25%/1%), Sept. 28, 2015; Tax Foundation, Facts & Figures 2026, Table 18 (State & Local Sales Tax Rates)
