Engine and drivetrain versions we test on the Lexus GS 300h
Each of the 1 Lexus GS 300h versions below — petrol, diesel, hybrid or electric as applicable — is one we routinely inspect.

Hybrid-specific checks on the Lexus GS 300h
- Regenerative braking. We test braking feel and look for the uneven wear that hybrid systems can mask.
- Battery cooling. Vents and cooling for the high-voltage pack are checked, as blocked cooling shortens battery life.
- Engine–motor transitions. On the road we check that the switch between petrol and electric drive is smooth and fault-free.
- 12V system. A flat or weak 12V battery causes baffling faults on hybrids; we verify it is healthy.
- High-voltage battery. We read the hybrid battery data for state of health and weak cells, since a tired pack is the costliest part to replace.

Lexus GS 300h: frequently asked questions
How much does a pre-purchase inspection of the Lexus GS 300h cost?
An on-site inspection of the Lexus GS 300h starts at 35,999 Ft for the Standard package, where you attend in person and we go through the findings with you at the car. The Digital Inspection Package costs 39,999 Ft and is carried out without you there, with the results sent as photographs, video and a written report by email. The inspection itself is identical in both, the call-out fee within Budapest is included, and there are no hidden extras.
What weak points on the Lexus GS 300h catch buyers out?
Most Lexus GS 300h examples are fine, but a few specific areas are worth checking before you commit. The usual suspects on a used Lexus GS 300h are regenerative braking, battery cooling and engine–motor transitions. None of these shows from the driver's seat, which is why buyers who search for mobile car diagnostic and inspection really need an on-site check — and our Lexus GS 300h inspection covers every one.
Can you inspect the Lexus GS 300h if I cannot be there in person?
That is exactly what the Digital Inspection Package (39,999 Ft) is built for. We attend the Lexus GS 300h on your behalf, carry out the complete inspection, and send you a detailed report with clear photographs and short video clips by email. It is the natural choice if you are buying from abroad, live in another city, or simply cannot make the viewing in person.
How long does an inspection of the Lexus GS 300h take?
A typical Lexus GS 300h inspection takes roughly one to one-and-a-half hours at the car, though a complex or high-mileage example can take longer. We work to a fixed checklist of more than 500 points and never hurry a car along to reach the next appointment. In most cases you will have the verdict the same day.
What exactly do you check on a used Lexus GS 300h?
We go right through the car: paint thickness panel by panel, the structure and underbody for corrosion or past repairs, the engine or battery and the drivetrain, full on-board diagnostics with live data, the suspension, steering and brakes, the interior and electronics, and a short road test. Across the hybrid versions of the Lexus GS 300h, the checklist is adapted to the exact car you are buying. If anything is unclear, just ask — we explain every finding in plain English.
Do you read the fault codes on the Lexus GS 300h?
Yes — a full on-board diagnostic scan is part of every inspection. On the Lexus GS 300h we capture both live and stored fault codes, including ones a seller may have cleared shortly before your viewing, and we read live data to catch systems that are struggling before any warning light appears. On electric and hybrid versions this also opens up the battery and charging data.
People search for car inspection service — is that what you do for the Lexus GS 300h?
Yes. Car inspection service is simply another way of describing what we do for the Lexus GS 300h: an independent, on-site inspection before you buy.
