This Pre purchase Car Inspection suits all shape cars with Modified Engine, ECU & Structures. Whether you have done Dyno Tuning on the car to boost performance or you have modified the Exhaust System, Suspension or anything else, this inspection will surely get to the bottom of it for you.

We have Specialised Modified Car Inspectors with complete knowledge in auto modification and we use state of the art Fault Diagnostic Computers to scan the ECU and detect all engine tuning related issues so count on us from A to Z to inform you of the true condition of the car before purchase.


We inspect all modified cars available in the Australian market as well as all imported modified cars from across the globe. We perform 100% Specialised Car Inspections, and each car gets inspected only by the right qualified inspector. Whether you have a Sedan, Hatch, Ute, Convertible, SUV, Van, 4WD, AWD or any other shape, we cover them all.

Have full confidence that your job is handled only by a specialist who knows everything about the vehicle and can bring all the issues to your attention before you pay for your next used car. To learn more, please visit Vehicles We Inspect.



Buying a modified car without inspection is the worst mistake anyone can make. We have seen many unsuspecting buyers losing big money on repairs right after purchase and normally the number of mechanical and ECU faults are much higher than in stock cars. Some modified cars have also been used as a toy and have been pushed to their limits by the previous owners although they look immaculate at the time of sale and here is when we can assist.

When we refer to stage tuning, someone’s stage one might give you more boost than someone else’s stage two and someone’s stage three might be weaker than someone else’s stage two. What is done during these stages also varies across the board and no two companies follow the exact same method or use the same parts.

Literally, there are hundreds of ways to tune cars and there are no market standards of what needs to be done or what parts need to be used. It is important to know what work has been done on the car before purchase and whether it has been legally approved since some very major modifications need to be registered depending on the state. A simple question from the seller and checking the registration status of the vehicle can give you the answer quickly.

A car can have so many big and small modifications, and we need to be informed what they are before we can do the inspection as literally, it is impossible to find all modified parts, especially the small and internal ones without being informed.

If the seller is unable to explain or the vehicle has been modified by another owner in the past, it should still be fine. We are unable to find what exactly has been done but we can tell you if the modifications have caused a problem somewhere, how the car is performing right now and what needs attention or repair before purchase.



When it comes to inspecting modified cars, we only appoint the right modified car inspector to take up the task and not a random inspector and this is one of the things that makes us different.

Our modified car inspectors have complete knowledge of how to modify cars themselves, tune the ECU, perform Dyno Tune and instal all aftermarket parts, so they know all the pros and cons of the job and can give you all the advice you need before purchase.

On top of that, modified car inspection is always done by TWO inspectors which makes the results even more solid. One inspector physically inspects the car, and another will go through tens of pages of computer diagnosis results, pictures and much more in the office which can take between 4 to 6 hours after the physical inspection to finish.

It is unique in the industry and Last Check is the only Australian company that offers such extensive jobs. Only @ Last Check

Using sophisticated diagnostic tools, we can tell you whether the mechanical modifications are doing any good or if they have negative effects on your car’s performance.

Even if the car is faulty and the seller has cleared the fault codes from the system before the sale, we can still find the hidden faults using our specialised scan tools. From body paint to suspension all the way to ECU tuning (chip tuning), count on us to bring up all the issues to your knowledge.

Structural Modifications can be exactly like Mechanical Modifications. In some cases, they improve the performance of the vehicle and in some cases, they work against it.

Whether it is a 4WD car with a suspension lift, a Disability Vehicle with disability equipment or a low rider with lowered suspension, if the job has been done professionally, the performance will be improved to match the owner’s expectations.

At the same time, especially in suspension modifications, an unprofessional job can have permanent negative effects on the vehicle such as non-reversible misalignment, bushes tearing, constant noise and big safety risks such as ABS and SRS malfunction.

With our Pre-Purchase Modified Vehicle Inspection, all areas of concern will be thoroughly inspected by our Specialised Modified Car Inspectors and will give you all the information you need before purchasing a structurally modified vehicle.

Engine Modifications such as Dyno Tuning are done on cars to improve performance and powertrain responsivity. Other mechanical modifications are done to improve other aspects of the vehicle; however they do not always go to plan.

Wrong Dyno Tuning or unprofessional turbocharger upgrades can work against vehicle performance and affect the ECU negatively and this happens frequently. This is the reason that normally the number of Computer Fault Codes in modified cars is significantly higher than in stock cars.

Engine tuning is a very meticulous job and requires special knowledge and sophisticated computers to see how the powertrain is affected and ensure that the performance has actually been boosted.

Just find your next used modified car and leave the hard work to us and be reassured that you will never lose money on a lemon when you have Last Check by your side.

Our main goal is to exceed our valuable clients’ expectations by providing a Vehicle Inspection Service unlike any other along with the best possible customer service.

Customer satisfaction is our number one priority, and we take this very seriously. Our Licenced Inspectors do not look at any client as a number, they look at each car as if they want to buy it for themselves. This is how they have been trained before joining our force.

Our premium inspection plans include more checks which makes a big difference however our basic packages are still very comprehensive.

For each inspection, your inspector will get a different checklist and the vehicle inspection will not end until the list is completed. The checklist intensity and inclusions are based on the inspection package you have chosen, and different plans have different inclusions.

After the inspection, your inspector will call you and give you a complete verbal report over the phone. You will then have the chance to ask all mechanical questions from the same mechanic who has inspected your vehicle.

Within 24 hours of the inspection, you will receive a 25 to 30+ Page Report along with Hundreds of Pictures, Vehicle History Report (Official PPSR Report), your payment receipt and all other associated documents. To see what the report looks like, please visit the Sample Report page.

If your plan includes Urgent SMS Report that can be added to your service before checkout, you will get the report normally on the same day via SMS. If you are making a phone booking, you can ask us to upgrade your report to urgent. To learn more about us, please visit Why Last Check & Only @ Last Check.
