How to Complete a Car Purchase in America: Step-by-Step
Buying or Selling a Car: What You Need to Know
Whether you are buying your first car or selling a vehicle you have outgrown, the process in America involves paperwork, state-specific rules, and a few potential pitfalls. This guide walks you through every step so you can close the deal with confidence.
Pro tip: Before you hand over any money, check the vehicle history with a VIN decoder — it takes two minutes and can save you thousands.
Buying from a Private Seller vs. Dealership
Private Seller
- Lower price — no dealer markup
- More risk — no lemon law protection in most states
- You handle all DMV paperwork yourself
Dealership
- Higher price — but financing options are easier
- Lemon law protection applies in many states
- Dealer handles most paperwork and registration
This guide focuses primarily on private-party transactions, which require more hands-on effort.
Documents the Seller Must Provide
- Vehicle title (also called a "pink slip" in some states) — signed over to the buyer
- Bill of sale — required in most states, sometimes with a specific state form
- Odometer disclosure — required by federal law for vehicles under 20 years old
- Smog/emissions certificate — required in states like California, New York, and others
- Maintenance records — not required, but helpful for the buyer
Title Issues to Watch
- A salvage title means the car was declared a total loss at some point
- A lien on the title means the seller still owes money — the lien holder must sign off
- No title at all? Walk away. Getting a bonded title is possible but complicated and risky
Documents the Buyer Needs
- Valid driver's license
- Proof of insurance — most states require this before registration
- Payment — cashier's check is safest for large amounts; avoid Venmo/Zelle for high-value deals
The Bill of Sale
A bill of sale protects both parties. Most states have a downloadable template on their DMV website. It should include:
- Full names and addresses of buyer and seller
- Vehicle details: year, make, model, VIN, odometer reading
- Sale price — some buyers try to record a lower price to save on sales tax; this is tax fraud
- Date of sale
- Signatures of both parties
- "As-is" statement if applicable (most private sales are as-is)
Important: Always inspect the car thoroughly before signing anything. Once you drive away, it is yours.
Step-by-Step Process
Step 1. Inspect and Test Drive
Meet in a public place. Check the exterior, interior, engine, and take it for a real test drive (highway speeds, not just around the block). Consider paying a mechanic $100–200 for a pre-purchase inspection.
Step 2. Negotiate the Price
Research fair market value on Kelley Blue Book (kbb.com) or NADA Guides. Use any issues found during inspection as leverage. More tips in our car negotiation guide.
Step 3. Complete the Paperwork
- Seller signs the title over to the buyer
- Both sign the bill of sale
- Seller provides odometer disclosure
- Exchange keys and payment
Step 4. Get Insurance
You must have insurance before driving the car legally. Call your insurance company or get a quote online. Many insurers can add a vehicle to your policy within minutes.
Step 5. Register at the DMV
Visit your local DMV (or use your state's online portal if available) with:
- Signed title
- Bill of sale
- Proof of insurance
- Your driver's license
- Payment for registration fees and sales tax
Typical costs:
- Registration fee: $15–$500+ depending on state
- Sales tax: 0% (Montana, Oregon) to 10%+ (some counties in California, Tennessee)
- Title transfer fee: $15–$75 depending on state
Step 6. Get Your Plates
Some states issue temporary plates immediately; others require you to transfer plates from a previous vehicle. You will receive your new registration and plates (or stickers) either at the DMV or by mail.
Taxes and Fees
Sales tax on used cars varies by state and county. A few key examples:
- California: 7.25% base + local (up to ~10.25%)
- Texas: 6.25%
- Florida: 6% + local
- Oregon: 0% (no sales tax)
- Montana: 0% (no sales tax)
Some states also charge a use tax if you bought the car in a state with lower tax.
Common Mistakes
- Not checking the VIN — always verify against the title and run a history report
- Skipping the inspection — hidden mechanical issues can cost more than the car
- Paying with cash without a receipt — always get a bill of sale and keep copies
- Not transferring the title promptly — deadlines vary by state (10–30 days); fines apply
- Forgetting to cancel the seller's insurance — sellers should notify their insurer after the sale

Frequently Asked Questions
Do I need a bill of sale when buying a car from a private seller?
Yes, a bill of sale is highly recommended and required in many states. It documents the purchase price, date, vehicle details, and both parties. Some states provide official bill of sale forms through their DMV.
Do I pay sales tax on a used car from a private seller?
Yes, in most states. Sales tax is paid when you register the vehicle at the DMV, not to the seller. The rate depends on your state and sometimes county or city.
How do I verify a clean title before buying?
Check the title for any brands such as salvage, rebuilt, or flood. Run a VIN check through the NMVTIS database or a vehicle history service. A clean title means no major damage history or financial liens.
What documents do I need to sell my car?
You need the vehicle title signed over to the buyer, a bill of sale, and in some states an odometer disclosure and smog or emissions certificate. Requirements vary by state — check your DMV.
