Peterson Auto Group is a multi-dealership chain in Boise with several locations selling new and used vehicles
Peterson Auto Group operates multiple dealerships across the Boise area, each typically focused on specific vehicle brands or types. The group includes locations that sell new cars, used cars, and trucks, with different dealerships handling different manufacturers. If you are shopping for a vehicle in Boise, you will likely encounter Peterson Auto Group as one of the larger dealer networks in the region.
Before you visit or contact any Peterson location, it helps to understand how car dealerships work, what paperwork you will need, and what questions to ask so you can make a decision that fits your budget and needs.
Key Takeaways
- Peterson Auto Group operates multiple locations in Boise, each typically selling specific brands, so confirm which location carries the type of vehicle you want before visiting.
- You will need proof of income, a valid driver's license, and proof of residence to finance a vehicle through any dealership.
- The price you see advertised may not include dealer fees, documentation charges, or taxes, so ask for a full breakdown before committing.
- Getting pre-approved for a loan from your own bank or credit union before visiting gives you negotiating power and a clear budget.
What documents you need to bring when you visit
When you go to a Peterson Auto Group location to look at vehicles or discuss financing, bring a valid driver's license and proof of residence (a recent utility bill, lease, or mortgage statement works). If you plan to finance, bring recent pay stubs or tax returns to show income, and your Social Security number so the dealership can run a credit check.
If you are trading in a vehicle, bring the title and keys. If you own the vehicle but still owe money on it, bring the loan paperwork so the dealership knows what payoff amount to expect. Having these documents ready speeds up the process and shows you are serious about moving forward.
How dealership pricing and fees work
The advertised price of a vehicle is rarely the final price you pay. Dealerships add documentation fees (sometimes called "doc fees"), which vary by location but typically range from a few hundred to over a thousand dollars. You will also pay sales tax, which in Ada County, Idaho is 6 percent, plus any local option tax that may explore in your specific city within Boise.
Before you sign anything, ask the dealership for an itemized breakdown of the total cost: the vehicle price, each fee they are charging, the tax amount, and any add-ons like extended warranties or paint protection. This breakdown should be in writing so you can review it and compare it to what you expected to pay.
Understanding financing through the dealership
Peterson Auto Group locations can arrange financing through their own lenders or through banks and credit unions they work with. The dealership acts as a middleman — they do not lend you money directly, but they connect you with lenders and handle the paperwork. The interest rate you receive depends on your credit score, income, and the loan term you choose.
Before you visit the dealership, check your credit score and get pre-approved for a loan from your own bank or credit union. Knowing your rate and loan amount in advance gives you a clear budget and lets you compare what the dealership offers. If the dealership's rate is higher, you can choose to use your own lender instead. Many dealerships will accept outside financing, though some may offer incentives if you finance through them.
What happens after you sign the paperwork
Once you sign the purchase agreement and financing documents, the dealership handles registration and title transfer with the Idaho Department of Transportation. This process typically takes one to two weeks. You will receive your title and registration documents by mail, and you can drive the vehicle home the same day you purchase it as long as you have proof of insurance.
Your insurance company needs to know about the new vehicle before you drive it off the lot. Call your insurer or add the vehicle to your policy online before you leave the dealership. If you do not have insurance in place, most dealerships will not let you leave with the car.
Questions to ask before you buy
Ask the dealership whether the vehicle comes with a warranty and what it covers. New vehicles typically come with a manufacturer's warranty, but used vehicles may have limited or no warranty unless the dealership offers an extended warranty for an additional cost. Ask how long the warranty lasts, what repairs it covers, and whether you can use any mechanic or only dealership mechanics.
Ask about the vehicle's history if it is used. The dealership should provide a vehicle history report (usually from Carfax or AutoCheck) that shows past accidents, title issues, and service records. Ask whether the vehicle has had any major repairs or if the odometer reading is accurate. If the dealership cannot or will not provide this information, that is a red flag.
What to do if you have a problem after purchase
If you discover a mechanical problem shortly after buying the vehicle, contact the dealership's service department. If the vehicle is under warranty, the dealership should repair it at no cost. If it is not under warranty and the dealership refuses to help, you may have recourse under Idaho's lemon law, which protects buyers of defective vehicles within a certain time frame after purchase.
Keep all paperwork related to your purchase and any repairs. If you need to file a complaint or pursue a lemon law claim, you will need documentation of the problem and proof that you gave the dealership a chance to fix it. The Idaho Attorney General's office can provide information about consumer protection laws if you believe you were treated unfairly.
Frequently Asked Questions
Can I return a car to Peterson Auto Group if I change my mind?
Most dealerships, including Peterson Auto Group locations, do not have a legal obligation to accept returns once you have signed the paperwork and driven the vehicle off the lot. Idaho does not have a mandatory "cooling-off" period for car purchases. However, some dealerships offer their own return policies, so ask about this before you buy.
What if I want to trade in my current car?
Bring your vehicle's title, keys, and maintenance records to the dealership. The dealer will inspect it and offer you a trade-in value, which they will subtract from the price of the new vehicle. You can negotiate the trade-in value just as you would negotiate the price of the new car. If you still owe money on your trade-in, the dealership will pay off that loan and handle the title transfer.
How long does it take to get approved for financing?
If you have all your documents ready, the dealership can usually get you a financing decision within a few hours. If your credit is complicated or your income is hard to verify, it may take longer. Some dealerships will let you drive the car home while they finalize the paperwork, but you should confirm this before you leave the lot.
What is gap insurance and do I need it?
Gap insurance covers the difference between what you owe on your car loan and what the car is worth if it is totaled in an accident. If you are financing most of the purchase price and putting down a small down payment, gap insurance can protect you. Ask the dealership what it costs and whether it is included in your financing package.
Can I negotiate the price at Peterson Auto Group?
Yes. The advertised price is a starting point, not a final offer. You can negotiate the vehicle price, the trade-in value, and the fees the dealership charges. Having pre-approval from another lender and knowing the vehicle's market value (check sites like Kelley Blue Book) gives you more negotiating power.
