Essential Online SUV-Buying Tips

• Get a vehicle history report and inspect before you buy. The FTC’s guide to buying a used car is a great starting point: https://consumer.ftc.gov/articles/buying-used-car
• Check for open recalls using the vehicle’s VIN: https://www.nhtsa.gov/recalls
• Validate delivery, return, and warranty terms on the seller’s official policy pages before purchase.
• Compare total cost of ownership across compact vs. full-size SUVs—fuel, insurance, maintenance, and tires can vary significantly.
• Line up financing and insurance quotes early to compare “out-the-door” numbers across multiple vehicles.

Bottom line Use two or three of these sites together: one for broad inventory, one for pricing transparency, and one with strong buyer protections. That combo will help you confidently land the right compact or full-size SUV at a fair price—without wasting time.
