How to Check a Used Car Before Buying: A Guide for First-Time Buyers

Buying a used car can be a smart and cost-effective decision, but it also comes with potential risks. Whether you’re a first-time buyer or just looking to avoid costly mistakes, this guide will walk you through everything you need to know before sealing the deal. With the right steps, you can confidently pick a reliable vehicle and avoid falling for lemons.

Set Your Budget (And Stick to It)

Before browsing listings, determine your maximum budget. Don’t just consider the purchase price—factor in taxes, registration, insurance, future maintenance, and repairs. A good rule is to keep at least 10-15% of your budget reserved for post-purchase expenses.

Pro Tip:

If you’re financing the car, get pre-approved for a loan first. It gives you better negotiation power and clarity on your spending limit.

Research the Right Model

Use tools like Kelley Blue Book, Edmunds, and Consumer Reports to research reliability, resale value, and common issues of the models you’re interested in. Pay attention to recall history and known mechanical problems.

Look For:

• High-reliability ratings
• Fuel economy
• Affordable replacement parts
• High owner satisfaction

Create a Checklist Before Viewing the Car

A thorough inspection starts with a solid checklist. Here are the key items you should bring:

• Flashlight
• OBD2 scanner (view our picks for OBD2 scanner)
• Tire tread gauge
• Magnet (for checking body filler)
• Notepad and pen
• Gloves and rag

You can also download a pre-purchase car inspection checklist or app to make this easier.

Inspect the Exterior

Walk around the car and look for signs of damage, repainting, or rust.

Key Areas to Check:

• Panel gaps (uneven gaps can indicate accident repair)
• Rust around wheel wells, under doors, and frame
• Cracks in headlights or tail lights
• Chips or uneven paint (may indicate touch-ups)

Check the Interior Thoroughly

Take your time inspecting the inside. Sit in all the seats and test all switches and buttons.

Key Checks:

• Seat condition and adjustability
• Dashboard lights (no warning lights should stay on after startup)
• A/C and heating system
• Window controls, mirrors, locks
• Odors (smoke or mold smells may signal water damage or abuse)

Examine Under the Hood

Even if you’re not a mechanic, basic checks can reveal a lot:

• Check oil and transmission fluid (look for proper levels and color)
• Inspect belts and hoses for cracks or wear
• Look for leaks or corrosion around the battery
• Check radiator coolant level and color (should be clean, not brown or rusty)

Take It for a Test Drive

Drive the car for at least 15–20 minutes, covering:

• City streets and highways
• Start-stop traffic
• Uphill and downhill routes

What to Watch/Listen For:

• Strange noises (rattles, squeaks, clunks)
• Smooth gear shifts (for automatics)
• Brake response (no vibration or pulling)
• Steering responsiveness

Ask for Service Records and Title

A responsible owner will have documentation of regular service, repairs, and oil changes. Also, ensure the title is clean—no salvage or rebuilt history.

Important Documents:

• Title and registration
• Maintenance records
• Bill of sale template (you can print a free one online)

Run a VIN Check

Use sites like Carfax or AutoCheck to run a Vehicle History Report using the VIN (Vehicle Identification Number). This report shows:

• Accident history
• Title status
• Odometer inconsistencies
• Number of previous owners

Get a Mechanic’s Inspection

If everything checks out so far, bring the car to a trusted mechanic for a full pre-purchase inspection. It usually costs under $150 and can save you thousands.

Negotiate Like a Pro

Use your research and inspection findings to negotiate a better price. Point out issues you found (like worn tires or upcoming service needs) and adjust your offer accordingly.

Quick Tip:

Never feel pressured. If the seller isn’t willing to negotiate or something feels off—walk away. There are always more cars.

Finalize the Paperwork

Once you agree on a price:

1. Sign a bill of sale
2. Complete the title transfer
3. Register the vehicle with your DMV
4. Contact your insurance company to activate coverage before you drive it home
