In Montana, there is no statewide "cooling-off period" or law that gives you a universal right to return a new car after purchase. The sale is typically final once you sign the contract. However, many dealerships offer their own short-term return policy, often ranging from 24 hours to a few days, as a customer satisfaction gesture. Your ability to return the vehicle hinges entirely on the specific policy offered by the dealership where you made the purchase.
The Legal Reality in Montana Montana law does not provide a mandatory return window for new vehicles. The concept of a "cooling-off period" that applies to some door-to-door sales does not extend to automobile transactions at dealerships. This is why it is absolutely critical to understand the paperwork you sign. The finality of the sale is emphasized in the retail installment sales contract.
Understanding Dealership Return Policies Because the law doesn't require it, any return option is a voluntary program from the dealer. These policies vary widely. Some may offer a no-questions-asked return within a very short timeframe, while others might have strict conditions, such as low mileage limits, no title work having been processed, and a restocking fee. You must get this policy in writing before you buy.
What to Do Before You Sign Your best defense is to ask pointed questions and review all documents:
Exceptions: Lemon Laws and Misrepresentation If the car has significant, recurring mechanical problems, Montana's Lemon Law may offer protection, but this is a lengthy legal process for repairing or replacing a defective vehicle, not a simple return. You also have recourse if the dealer committed fraud or misrepresented the car's condition.
| Dealership Policy Type | Typical Timeframe | Common Conditions | Likelihood of a Full Refund |
|---|---|---|---|
| "Satisfaction Guarantee" | 3-7 days | Very low mileage (e.g., under 300 miles), no damage, all paperwork included. | High, but may have a restocking fee. |
| Short-Term Exchange | 24-72 hours | Vehicle must be in like-new condition; often an exchange for another car on the lot, not a refund. | Low; goal is to keep the sale within the dealership. |
| No Formal Policy | N/A | Sale is final upon signing. Return only considered for demonstrable fraud or major undisclosed defects. | Extremely low without legal action. |
| Lemon Law Application | Varies by case | Applies only after multiple repair attempts for a serious issue covered by the manufacturer's warranty. | Results in repurchase or replacement, not a straightforward return. |
Ultimately, the responsibility is on you, the buyer, to perform due diligence before finalizing the purchase.

Check your paperwork. Right after I bought my truck in Billings, I went through every page. I found a single paragraph titled "Return Policy" buried in the back. It gave me three days, as long as I kept the miles under 250. I didn't need it, but knowing it was there made me feel a lot better. Always ask for that policy and make sure it's written down before you shake hands.

Montana law is pretty clear: a car sale is final. There's no take-backsies. The only way you're getting out of the deal is if the dealership itself promised you a return window in writing. You need to look for that specific clause in your contract. Without it, you're basically hoping for them to be nice, which isn't a great strategy with that much money on the line. Your leverage disappears the moment you drive off the lot.

You need to read the fine print. I made the mistake of assuming there was a grace period. There isn't. Call the dealership's finance manager directly and ask, "What is your official return policy?" Do not accept a verbal promise. Tell them you need to see the terms in the purchase agreement. If they don't have one, you have to be 100% certain you want that car, because you're stuck with it, flaws and all.
