Here is a handy guide from the staff at PrivateAuto. It includes helpful tips for buying a used car in Idaho.

Gathering the Documents

Certificate of Title

Complete the following on the reverse side of the title:

  • Your name and address.
  • Your signature.
  • Seller’s signature.
  • Odometer disclosure if the car is less than 10 years old.

Odometer Statement

If your car is less than 10 years old, complete the odometer statement on the title.

If there’s no room on the title, complete the Federal Odometer Disclosure Statement.

Bill of Sale

Although Idaho doesn’t require a bill of sale, it’s a good idea to have one. It provides documentation of the transaction and can make things go smoother with registration and title transfer.

When you buy a car through PrivateAuto, the seller will have a bill of sale you can sign directly from the app.

Research the Title

The National Insurance Crimes Bureau website will help you verify the car:

  • Isn’t reported stolen.
  • Wasn’t declared a total loss in an insurance claim.

Mechanical Inspection

Used cars rarely have a warranty. You’ll want to make sure there aren’t any hidden mechanical problems before you buy.

Find an ASE Certified mechanic. A mechanic with this credential is skilled with most cars and light trucks.

Vehicle History Report

A vehicle history report can reveal if the car was in an accident, damaged in a flood or storm, reported stolen, and more.

When you buy through PrivateAuto, some sellers may provide a report from AutoCheck.

Registering the Car In Your Name

Idaho requires the seller to remove the license plates before finalizing the sale.

You’ll need to register for new plates and apply for a new title in person at the county assessor’s office.
