Used Car Buying Guides

Everything you need to buy a used car with confidence.

🔍 How to check a VIN history report

A VIN history report reveals accidents, ownership transfers, odometer readings, and service records. Always run a CARFAX or AutoCheck report before purchasing any used vehicle. Look for clean titles, single-owner histories, and consistent service records.

💰 How to negotiate a used car price

Research the market value using CarGurus, KBB, and Edmunds before you visit a dealer. Know your walk-away price. Start 10-15% below asking and be prepared to walk if the dealer won't meet fair market value. Off-lease vehicles and end-of-month visits tend to yield better deals.

🔧 Pre-purchase inspection checklist

Before buying any used vehicle, have an independent mechanic perform a pre-purchase inspection (PPI). Cost: $100-150. Inspect the engine bay for leaks, check all four tires for even wear, test all electronics, and take a test drive on the highway to check for vibrations.

📋 Understanding depreciation by model

Trucks and SUVs depreciate slower than sedans. Japanese brands (Toyota, Honda, Mazda) hold value better than most European brands at 3-5 years old. Electric vehicles depreciate faster in the near term due to battery uncertainty, but models from Tesla and Chevrolet have stabilized.

🛡️ Extended warranties: when they're worth it

Third-party extended warranties are rarely worth their cost. Manufacturer certified pre-owned (CPO) programs offer better coverage at a fair price. If the vehicle is still under the original factory warranty, that coverage transfers to you — check the in-service date.
