What Is a Pre Purchase Inspection (PPI)? Why You Should Never Buy a Used Car Without One

Don’t Get Scammed When Buying a Used Car

Buying a used car is a smart way to save money, especially in Bangladesh. But looks can be deceiving. A shiny body and smooth test drive might hide serious problems that cost you thousands of taka later.

That’s where a Pre Purchase Inspection (PPI) comes in.

This guide explains why a PPI is essential, how it works, and where to get one in Dhaka. Whether you're a first-time buyer or an experienced car owner, this article will help you avoid costly mistakes and drive away with confidence.

What Is a Pre Purchase Inspection (PPI)?

A Simple Definition

A Pre Purchase Inspection (PPI) is a complete vehicle check done before you buy a used car. It’s performed by a trained mechanic who inspects the car’s engine, body, brakes, suspension, electronics, and more. The goal is to find any issues the seller might not mention—or may not even know about.

It helps you make an informed choice before spending your money.

Who Performs a PPI?

A proper PPI is done by a professional mechanic, not the seller or a friend. Choose a technician who is certified, has experience with multiple car brands, and is independent from the seller.

In Dhaka, trusted centers like Biswas Automobiles offer expert inspection services. Our mechanics are trained to detect hidden issues and give you honest feedback.

Why You Should Never Skip a PPI Before Buying a Car

Skipping a PPI might save you a small fee now, but it can cost you a lot more in repairs later. Here's why it matters:

It Finds Hidden Problems

Many cars hide issues that don’t show during a test drive. A proper inspection may reveal:

Engine oil leaks
Brake wear
Worn-out tires
Poor suspension
Electrical faults
Signs of previous accident damage

These problems could make the car unsafe or expensive to repair.

It Helps You Negotiate the Price

If the PPI finds issues, you can use the report to:

Lower the price
Ask the seller to fix problems
Walk away from a bad deal

This gives you better control and helps you know the true value of the vehicle.

It Protects Your Safety

A car may look fine but still have safety issues like:

Bad brakes
Airbag faults
Weak suspension
Worn tires
Power steering failure

These can put you and your family at risk. A PPI helps you stay safe.

It Confirms the Seller’s Claims

Some sellers say:

“The car is accident-free.”
“It’s in perfect condition.”
“Everything is original.”

A PPI helps you check if this is true. If a seller refuses to allow a PPI, it may be a red flag.

It Gives You Peace of Mind

Knowing your future car is in good shape helps you feel confident in your purchase. You’ll also be better prepared when it’s time to transfer ownership or get insurance.

When Do You Need a PPI?

Always Before Purchase – Not After

Many buyers skip the inspection, sign the papers, and regret it later. A PPI must always be done before you make any payment or legal commitment.

Especially With Used or Certified Pre-Owned Cars

Even certified pre owned cars can have problems. Just because a dealer gives a warranty doesn't mean every issue is covered.

Get a PPI whether you're buying from:

A private seller
A used car dealership
A showroom with “certified pre owned” tags
