Why PPI is an Essential Step Before Buying a Car

Computer Diagnostics Are Important!  But Not Enough...

Many people believe it is enough to connect a scanner and check for fault codes. In reality, this approach is far from sufficient.

A computer cannot detect many mechanical problems, especially if the issue has not yet reached a critical stage or is not monitored by the vehicle’s electronic systems at all.

For example:

❕oil leaks;

❕coolant leaks;

❕suspension wear;

❕accident damage;

❕poor-quality body repairs;

❕hidden engine issues.

Very often, sellers carefully prepare a vehicle before selling it. The engine bay is steam-cleaned to remove traces of oil and fluids. Afterward, parts are treated with shine-enhancing products, making the engine appear almost brand new.

Visual Inspection of the Engine Bay

A truly experienced mechanic can practically “read” an engine like Sherlock Holmes.

The condition of the engine bay can reveal:

🔘 how well the vehicle was maintained;

🔘 whether someone attempted to hide leaks;

🔘 signs of overheating;

🔘 evidence of poor-quality repairs;

🔘 whether temporary fixes were used instead of proper repairs.

Inspection of Technical Fluids

The color, smell, and consistency of fluids can reveal a great deal about a vehicle’s condition.

We inspect:

🔘 engine oil;

🔘 coolant;

🔘 brake fluid;

🔘 power steering fluid;

🔘 transmission fluid.

Sometimes, fluid inspection alone can uncover serious engine problems or signs that quick-fix additives were used to temporarily mask issues.

Detailed CarFax Report Analysis

Before every inspection, we carefully review the CarFax report.

If the seller does not provide one, we order it ourselves.

But most importantly, we help properly interpret the report.

For someone outside the automotive industry, many entries may appear insignificant, while in reality they can be major red flags.

Extended Inspection for High-Value Vehicles

For expensive and premium vehicles, we recommend an extended inspection.

Paint Thickness Gauge Inspection

Many people assume that if an accident does not appear on CarFax, the vehicle has never been involved in a collision.

Unfortunately, that is not always true.

Some vehicles:

🔘  are repaired without involving insurance companies;

🔘  are restored privately;

🔘  spend years in rental fleets;

🔘  have undocumented damage.

Using a paint thickness gauge, we inspect the paintwork and can determine:

🔘  which panels were repainted;

🔘  where body repairs were performed;

🔘  the quality of the restoration work.

Undercarriage Inspection

We raise the vehicle and thoroughly inspect the entire underside.

We check:

🔘  suspension components;

🔘  engine and transmission leaks;

🔘  bushings and mounts;

🔘  steering components;

🔘  exhaust system;

🔘  impact damage and underbody repairs.

The most expensive problems are often hidden underneath the vehicle.
