Wisconsin has laws to protect residents when buying a car from a private seller. This guide will take you through the steps.

Step 1 - Gather Documents

Certificate of Title

Complete the reassignment section on the back of the title.

  • Odometer disclosure.
  • Your name and address.
  • Your signature and date.
  • Seller’s signature and date.

Bill of Sale

Wisconsin doesn’t require a bill of sale. It’s still a good idea to have one for your records. It can help if any tax or legal issues come up.

PrivateAuto provides an electronic bill of sale form and state-specific documents. You can fill them out and sign right in the app.

Step 2 -  Get a Vehicle History Report

A vehicle history report can show you:

  • Title liens.
  • Reported stolen.
  • Fire or flood damage.
  • Maintenance records.
  • more.

PrivateAuto partner AutoCheck delivers the most value for the money. With data from Experian, you get a complete picture of the car’s history.

Step 3 - Get a Mechanical Inspection

You’re buying the car as-is, without a warranty. You pay for any repairs after the sale.

Make sure the car doesn’t have hidden mechanical problems.

Get an inspection from an ASE Certified mechanic. The credential shows that the mechanic is skilled at inspecting and repairing most cars and light trucks.

Step 4 - Complete the Purchase

When you register the car, you’ll get temporary tags to display until the license plates arrive.

You will also need to:

  • Get insurance.
  • Apply for a new title.
  • Pay sales taxes.
