Common Mistakes to Avoid When Buying a Used Car

Purchasing a used car is a smart financial move that can save you thousands of dollars in depreciation. However, without a clear strategy, that “bargain” can quickly turn into a mechanical nightmare. To ensure you drive away with a reliable ride instead of a lemon, avoid these common mistakes.

1. Skipping the Pre-Purchase Inspection (PPI)

This is arguably the biggest mistake a buyer can make. Even if a car looks pristine and the seller seems trustworthy, hidden issues like frame damage or engine sludge aren’t visible to the naked eye.

• The Fix: Always take the car to a trusted, independent mechanic for a full inspection before any money changes hands.

2. Neglecting the Vehicle History Report

A car might have a clean title but a dark past. Ignoring reports from services like CARFAX or AutoCheck means you could be buying a car that was previously involved in a flood, a major accident, or had its odometer rolled back.

• The Fix: Get the Vehicle Identification Number (VIN) and run a report to verify the car’s service history and accident record.

3. Shopping Based on Monthly Payments Only

Dealerships love to talk about “monthly payments” because they can stretch a loan over 72 or 84 months to make an expensive car look affordable. This often results in paying thousands more in interest.

• The Fix: Negotiate the total purchase price of the car first. Only discuss financing once you’ve agreed on the actual value of the vehicle.

4. Failing to Set a Realistic Budget

Many buyers forget that the cost of a car is more than just the sticker price. You need to account for:

• Sales tax and registration fees.

• Insurance premium increases.

• Immediate maintenance (new tires, oil changes).

• The Fix: Aim to keep your total car-related expenses under 15-20% of your take-home pay.

5. Falling in Love Too Fast

Emotional buying leads to ignoring “red flags.” If you decide you must have a specific car before you’ve even checked the oil, you lose your power to negotiate.

• The Fix: Be prepared to walk away. There are millions of used cars on the market; don’t settle for one that doesn’t meet your safety or financial criteria.

6. The “Short” Test Drive

A ten-minute drive around the block isn’t enough to reveal how a car performs. You need to know how it handles at high speeds, how the brakes feel during a sudden stop, and if the electronics work.
