BUYERS BEWARE  -Don't buy a lemon of a vehicle!

We are here to help!                                                                                                                                                                                                  *Video Courtesy of Seven News

Don't get caught out with buying a lemon of a vehicle.

We actively complete pre-purchase inspections on all used auction vehicles both large and small on our client's behalf to inspect and report all defects found before making your initial bid.

All too often we see people essentially buying at auction via images supplied by the auctioneer house.  This is absolutely not recommended without engaging a professional to inspect the vehicle on-site.  Whilst most auctioneer houses do not allow potential buyers to test drive the vehicles, we are able to carry out a completely non-invasive assessment of the subject vehicle to ensure you are actually getting what you are paying for.

rest assure that if we are uncertain of anything or something doesn't seem right, we will always let you know.

Why Choose Us?

• Digital Paint Testing
  We are equipped to test the paint thickness to determine any possible pre-existing repairs, body filler, or any other nasty surprises under the paintwork.
  
  
• Diagnostic Testing 
  We provide computer diagnostics scanning, and comprehensively check all available onboard modules to discover any hidden faults. We can reset any inactive faults and monitor the vehicle for the remainder of the inspection.
  
  
• Complimentary Valuations
  We provide you with a valuation report, with attached market examples, to ensure our clients are paying within the expected market value.
  ​
• Combustion Leak Testing (head-gasket condition)
  ​Our clients now have the option of a combustion leak test! The combustion leak test detects any presence of Co2 (carbon dioxide) within the cooling system.​ The presence of Co2 indicates there is an internal combustion leak within the engine.
