Transportation and Vehicle Ownership · Chapter 2
Choosing, checking and verifying a vehicle
Buy the vehicle that meets the household's actual transportation requirements, not the one that produces the strongest emotional response during shopping.
Requirements first
Define what the household actually needs
Before visiting a dealer or browsing listings, specify the minimum vehicle requirements. Shopping without a requirements list leads to buying more vehicle than the household needs because features are attractive, or less vehicle than it needs because the price looked right in the moment.
| Category | Questions to answer |
|---|---|
| People | How many adults? How many children? How many car seats? |
| Accessibility | Walker, wheelchair, transfer height, mobility device, service animal? |
| Cargo | Groceries, work tools, pet crates, sports equipment? |
| Driving | Daily miles, highway, rural roads, snow, mountains, towing? |
| Energy | Gasoline, diesel, hybrid, plug-in hybrid, or fully electric? |
| Parking | Garage dimensions, driveway, street parking, charging access? |
| Budget | Purchase price, insurance, fuel or electricity, maintenance, tires, registration? |
The cheapest vehicle to buy is not necessarily the cheapest vehicle to own. Fuel, insurance, maintenance, tires, repairs, registration, and reliability all affect the real cost over time. A vehicle that fits the household's actual passenger, cargo, driving, and budget requirements is a better purchase than one that merely looked appealing on the lot.
Federal research tools
Use NHTSA and EPA before shopping
NHTSA provides 5-Star Safety Ratings, recalls, complaints, and driver-assistance information for vehicles. These are useful comparison data points, though no single rating number should be the only reason to buy a vehicle. Fit, size, use, reliability, and condition also matter.
EPA provides standardized fuel-economy labels for new vehicles showing city, highway, and combined efficiency, annual fuel-cost estimates, and EV range and charging information where applicable. EPA emphasizes that actual mileage varies by driving behavior, weather, road conditions, and vehicle condition. The value of the label is standardized comparison: comparing two vehicles using the same test methodology rather than manufacturer marketing claims.
What these tools do and do not tell you
NHTSA safety ratings compare vehicles within the same weight class. A 5-star rating does not mean a vehicle is safe in every possible crash scenario. It means the vehicle performed well in the specific tests conducted.
EPA fuel-economy numbers are standardized comparison tools, not guarantees. A vehicle rated at 30 MPG combined may deliver 25 or 35 depending on how and where you drive. Use the labels to compare vehicles against each other, and use your own fuel records to measure actual household cost.
Both tools are free. NHTSA's vehicle safety resources are available at nhtsa.gov. EPA fuel-economy data is available at epa.gov/fueleconomy and at fueleconomy.gov.
Used vehicle checks
Three checks that answer different questions
A used vehicle needs three independent verifications, and each answers a different question. Skipping any one of them leaves a different risk unchecked.
1. NHTSA recall check
Enter the VIN at nhtsa.gov/recalls to check for unrepaired safety recalls. A used vehicle can have an active recall the seller has not mentioned. If the results include a "Do Not Drive" or "Park Outside" instruction, follow that instruction before doing anything else. Safety recall repairs are generally provided without charge through the manufacturer's recall process.
2. Title and vehicle history
The Department of Justice's National Motor Vehicle Title Information System (NMVTIS) provides consumer access through approved providers to title state information, title dates, odometer readings, title brands, and salvage or total-loss indicators. This tells you whether the vehicle has been branded salvage, flood, or junk by a previous state, and whether the odometer history is consistent. NMVTIS is not a complete mechanical history or a record of every accident. It is designed around core title, fraud, and salvage indicators. Use it alongside inspection, not instead of it.
3. Independent mechanical inspection
The FTC recommends having a used vehicle inspected by an independent mechanic before purchase, even if the dealer states the vehicle has been inspected or "certified." The key word is independent: a mechanic the buyer chooses, not one the seller provides. This inspection checks the physical condition of the vehicle in ways that neither a history report nor a recall check can.
The used-vehicle verification principle
A vehicle-history report is not a mechanical inspection. A mechanical inspection is not a title-history report. A recall check is neither. A clean-looking exterior does not answer any of these questions. Use all three when purchasing a used vehicle.
Odometer fraud
NHTSA advises used-car buyers to compare title mileage, the current odometer reading, maintenance and inspection records, physical wear, and available vehicle history for consistency. Digital odometers can be altered. A vehicle with 40,000 miles on the odometer but brake pads, tires, and seats that look like they have seen 120,000 miles warrants further investigation. The comparison across multiple data sources is what catches discrepancies.
The FTC Buyers Guide
The FTC requires covered used-car dealers to display a Buyers Guide on used vehicles offered for sale. The Guide identifies whether the vehicle is sold "as is" or with a warranty, lists major systems, and reminds the buyer to obtain an independent inspection and vehicle-history information. The Used Car Rule has exceptions, including certain vehicle categories, and does not apply to every private sale.
There is no universal federal three-day return right
The FTC states that federal law does not require dealers to give buyers three days to cancel an ordinary used-car purchase. Whether a vehicle can be returned depends on the dealer's own policy and applicable state law. Do not assume a return right exists without verifying the specific terms of the sale.
After purchase
Recall monitoring is not one-time
NHTSA currently recommends checking for open recalls at least twice a year. A vehicle with no recall today can receive one tomorrow. New defects are discovered, patterns emerge from consumer complaints, and manufacturers issue recalls on vehicles that have been on the road for years.
NHTSA's SaferCar app can monitor vehicles, tires, and car seats for recall notifications. This is an optional convenience tool. Recall monitoring can also be performed manually by entering the VIN at nhtsa.gov/recalls on a regular schedule.
When a recall notice arrives
Read the recall notice completely, including any special instructions.
If the notice includes a "Do Not Drive" or "Park Outside" instruction, follow that instruction immediately.
Contact the manufacturer's dealer network to schedule the recall repair.
Safety recall repairs are generally provided without charge through the manufacturer's recall process.
Keep the registration address current so recall notices can reach you.
Report a safety problem
NHTSA accepts consumer safety complaints. These complaints can help the agency identify patterns that may warrant investigation or a recall. If a vehicle has a serious safety defect, do not wait for a recall to appear. Seek repair or evaluation and report the problem to NHTSA. The complaint process is available through nhtsa.gov.
