Arizona Automobile Purchase Agreement Overview
An automobile purchase agreement in Arizona is a pre-sale contract that establishes all terms and conditions before the vehicle transaction closes. This is different from a bill of sale, which simply records a completed sale. The purchase agreement protects both parties by defining the price, financing, inspection contingencies, warranty terms, and conditions for closing.
Arizona's vehicle sales tax combines a 5.6% TPT rate with local taxes, often totaling 8-10%. Arizona's Lemon Law covers new vehicles within the warranty term or 2 years/24,000 miles, whichever comes first.

Purchase Agreement vs. Bill of Sale
An automobile purchase agreement is signed BEFORE the sale closes and establishes conditions (financing approval, inspection results, lien payoff). A bill of sale is signed AFTER/AT closing as a receipt. For complex transactions involving financing, trade-ins, or lien payoffs, a purchase agreement provides far more protection than a bill of sale alone.
What to Include in Your Arizona Automobile Purchase Agreement

- Emissions Compliance: Required in Maricopa and Pima counties — seller must provide valid emissions certificate
Key Provisions for Arizona
Financing Terms
If the buyer is financing the purchase, the agreement should include a financing contingency allowing the buyer to cancel if they cannot obtain financing within a specified period. Include the anticipated loan amount, interest rate, and term.
Lemon Law Protection
New vehicles (within warranty term or 2 years/24K miles). Arizona's lemon law covers only new vehicles. For used vehicle purchases, include thorough inspection contingencies in your agreement.
VIN Verification & History
The agreement should require the seller to verify that the VIN matches all documents, disclose whether the vehicle has a salvage or rebuilt title, and allow the buyer to obtain a vehicle history report. This protects against odometer fraud, undisclosed accidents, and title washing.
Lien Payoff Process
If the seller has an outstanding loan on the vehicle, the agreement must address how the lien will be satisfied. Typically, the buyer's payment goes through escrow to pay off the lien first, with the remainder going to the seller. The seller must deliver a clean title within a specified timeframe.
