Wyoming Seller Guide: Everything You Need Before Selling Your Car to a Private Buyer Wyoming Seller Guide: Everything You Need Before Selling Your Car to a Private Buyer

Selling a car in Wyoming doesn't have to be a tough process with multiple trips to the dealership and low offers on vehicle trade-ins. You've got a vehicle that's crossed the snowy mountain passes over Teton mountains or driven across the open highway across the high plains of the state and deserve to get the reasonable value of your car when you've completed the sale.

By selling your vehicle through a private sale, you are in control of the sale, you determine the price, when sold and who you'll shake your hand with at the completion of the transaction. However, it takes hard work to sell your vehicle through a private sale. You should know the rules that apply to Wyoming, such as the requirement to have the correct documents notary stamped and the proper procedures for disposing of license plates.

This guide will provide you with everything you need to ensure a smooth, safe and profitable sale. We will describe all the necessary documents that are required for the sale of your vehicle and create a step-by-step plan to sell your vehicle, and we will even demonstrate how using modern platforms, such as KarKiosk will help you avoid the hassle of selling your vehicle privately.

The Step-by-Step Guide to Selling Your Car Privately

The success of your sale will ultimately depend on the level of preparation that you have done and how you present your vehicle to prospective buyers. By following these proven steps you will be able to attract true buyers for your vehicle and sell it for a fair price.


1. Prepare Your Vehicle

The first impression is important. Take the time to wash the outside of your vehicle and vacuum the inside, as well as clean all of the surfaces inside and out. If you are selling a vehicle that is worth a lot of money, think about hiring a professional detailer. Also, fix little things such as burnt-out lights or squeaky windshield wipers. If your car looks clean and has been properly maintained, then it gives buyers an impression that you have taken care of your car from a mechanical standpoint as well.

2. Take Excellent Photos

When buyers are looking to purchase a vehicle they will be looking at pictures, so it is important for you to take 15-20 quality pictures of your vehicle, with good lighting either early in the morning or late in the afternoon. Take pictures of the exterior, interior (including spots for seating), dashboard, trunk, and engine. Be sure to focus on any options or special features of the vehicle, and if you have any minor dents or scratches, please include those in your pictures as well.

3. Price it Correctly

When you first list your vehicle for sale you must price it correctly. If you over-price your vehicle then it will not be viewed by many potential buyers. On the contrary, if you under-price your vehicle then you will lose money when you sell it. To help determine the proper price to sell your vehicle, consider using a market valuation tool that will show you how much similar vehicles are being sold for in Casper, Cheyenne, or Jackson.

4. Write a Compelling Listing

Your vehicle listing must contain a clear and accurate description of the vehicle. The description should include: vehicle make, model, year, mileage, and trim level. It’s also a good idea to describe how you used the vehicle while you owned it. An example might be: "commuted to Cheyenne mostly along the interstate." Lastly, list recent maintenance done on the vehicle, such as new tires or brake pads.

5. Communicate with Buyers as Offers Come In and Schedule Test Drives.

Once you start receiving offers on your vehicle, it is important to communicate safely. Additionally, you'll want to screen out any low-ball offers and schedule appointments with the serious buyers. Finally, always conduct test drives in public, safe locations.


Understanding Paperwork & Documentation

The state of Wyoming has very strict guidelines regarding transferring the title of a vehicle. Misplacing documents or incorrectly completing documentation can negatively impact your sale and create future issues regarding the title transfer. Before handing over the keys to your vehicle, be sure to collect the following documentation:

Documentation Sellers Must Provide

The Certificate of Title

In order for a person to legally transfer a vehicle, he/she needs to have a clear title to the vehicle. If you still owe money on a vehicle, you will need to pay off the loan in order to obtain a lien release from your bank before selling the car.

When signing over a Wyoming title, it is necessary to complete the "Assignment of Title" section located on the back of the title, which includes filling in the buyer's full name and address, the odometer reading, date of sale and purchase price. The owner's signature must also be notarized to be valid; therefore, do not sign the title before going to a notary.

A Notarized Bill of Sale

You will also need to provide a Bill of Sale. The Bill of Sale will serve as your official receipt for the sale of the vehicle, and will also protect both the seller and buyer of the vehicle. Make sure that the Bill of Sale includes the model year, make, model, VIN, price paid for the vehicle, and date of sale. Both the seller and the buyer will sign the Bill of Sale in front of a notary.

Odometer Disclosure Statement

You must provide the odometer disclosure statement if you are selling a vehicle that is less than ten (10) years old; both federal and state law require that the exact odometer reading of the sold vehicle be disclosed, and the odometer reading is typically already documented on the vehicle title. Regardless, be sure to disclose all of the facts in order to avoid a future claim of fraud.

Documents Buyers Need to Handle

After the sale,To legally operate the vehicle, the buyer must bring the notarized title and bill of sale to the local county clerk's office, pay the sales tax on the purchase price, and apply for a new title and registration. The buyer will need to provide proof of insurance before they can legally drive the vehicle.

The Importance of Safe Transactions

Selling your vehicle can involve significant money and meeting people you don’t know; therefore, you need to take steps to protect yourself, your personal information and your finances.


Meet in a safe place

Never invite a buyer to your home. Meet in an area that is well trafficked and well-lit, such as a busy grocery store parking lot, bank, or local police station. Some police departments in Wyoming encourage their residents to use the lobby or parking lot of their department for online classified transactions.

Verify the buyer's identity

Before handing over the keys for a test drive, ask to see the buyer's driver's license. Take a quick picture of the license with your smartphone and send the image to a family member or friend. Include the location in your text message. Accompany the buyer on the test drive, so you can answer questions and ensure your vehicle returns safely.

Receive payments securely

Do not accept personal checks because they can bounce after the vehicle has left your possession. Accepting cash for a low-value vehicle is safe; however, transporting and handling large amounts of cash has its risks. The best way to accept payment would be to meet with the buyer at their bank and watch the bank teller prepare the cashier's check for you. Bank wire transfers are also a quick and secure method to receive payment.

Traditional vs. KarKiosk

For many years, when a person sold a car they generally used newspaper advertisements and "For Sale by Owner" signs displayed in the windshield. Then there was an influx of generic online classified advertising which created a space for scammers and spam. Nowadays, there are more utilitarian web based platforms than ever to help facilitate the purchase and sale of vehicles.

FAQs about Cars for Sale by Owner

Do you have to leave the plates on the car for your buyer? toggle

No. In the state of Wyoming, the plates belong to you, as the seller, not the vehicle itself. Before the buyer can drive away with the vehicle, you must remove your plates. You may then transfer the plates to your next vehicle or return them to the County Treasurer.

Will I be collecting sales tax from the buyer? toggle

No. Private sellers do not collect sales tax in Wyoming. The seller will record the purchase price on the notarized title and Bill of Sale and the buyer will pay the sales tax to the County Clerk, when they register the vehicle.

Is a Safety Inspection Required in Wyoming? toggle

No. Wyoming does not require safety inspections of private vehicles sold or emissions testing of private vehicles sold. The vehicle is sold "as-is." If the car is currently titled in another state, then the buyer will need to have a basic VIN check conducted by law enforcement before registering the vehicle.

How do I transfer my liability once the car has left my possession? toggle

Two things need to occur in order for you to transfer liability. First, you MUST remove the license plates from the vehicle. Second, you MUST have both a notarized title and Bill of Sale with appropriate signatures and dates in front of/notarized by a notary public. Once those two documents are completed with a notary public, your liability for parking tickets, tolls or accidents will no longer exist.

What do I do if I lost my title? toggle

You cannot legally transfer ownership of your vehicle without a title in Wyoming. If you lost your title, or if your title is damaged, you must visit your County Clerk's office and apply for a duplicate title prior to listing the car for sale.
