We believe in complete transparency. This is the step-by-step process behind the mobile pre-purchase car inspection Cherrybrook buyers trust.
STEP 01Preparation and database check
We gather the seller's contact details, your name and email, and the registration number. We check our internal database for previous inspections, then check written-off status, stolen-vehicle reports, finance owing and accident history. We prepare a make-and-model checklist, such as timing seals, valve-cover and oil-filter-housing gaskets on a BMW 1 Series.
STEP 02Arrival and visual assessment
At a private home, property or car park, we check paint, panel gaps, repairs, rust, underbody oil, coolant and transmission leaks, VINs, interior wear, lights, windows, basic functions, hoses, belts and evidence of recent cover-up cleaning.
STEP 03Pre-start diagnostic scan
Our professional computer scans the engine, transmission, powertrain, body and other modules for stored, pending and history codes. We pay special attention to oil-pressure faults, compare odometer readings across modules, and test battery voltage, CCA and state of health.
STEP 04Thermal-camera cooling check
Thermal imaging examines the radiator, hoses and engine block. Cold spots reveal blockages; abnormal heat transfer can point to a hose or cooling-system issue. This is a tool that 99% of other inspectors in Cherrybrook do not use.
STEP 05Live data analysis
Once started, we monitor engine oil pressure, MAF, coolant and oil temperature, sensors, individual-cylinder misfires, transmission temperature and overheating history. For diesel vehicles we can also check DPF soot load, EGR operation and turbo boost pressure.
STEP 06Physical and mechanical inspection
We inspect timing, valve-cover, oil-filter-housing, oil-pan and rear-main seals with a flashlight and inspection mirror. We check oil level and condition, use UV dye where applicable, inspect the underbody, suspension, steering, mounts, vital fluids, engine noise, brakes, tyres and every major leak point.
STEP 07Dynamic test drive
We use a route around Cherrybrook with city streets, bumps and highway speeds on New Line Road or the M2. We monitor oil pressure under load, transmission shifts, engine response, suspension feedback and braking stability.
STEP 08Verdict and report
If you are present, we show you the issues and explain whether the car is worth buying. If you are not, we send a detailed written report with photos and videos by the same evening.
