We Conduct a Thorough Car Pre-Purchase Inspection in Sydney

​​Buying a car is a life moment that is joyous and exciting. Whether you’re considering a second-hand vehicle from a dealer or private seller, it’s advisable to get a car pre-purchase inspection in Sydney. It takes years to save up enough cash to acquire a vehicle or pay the deposit to finance a larger purchase. For this reason, you must protect your investment and ensure the seller is not duping you. Double Chex offers a mobile, professional car pre-purchase inspection and provides you with a detailed report that allows you to make an informed decision about spending your money on a particular vehicle. 

The Benefits of a Pre-Purchase Car Inspection Service

While we’d all love to drive high-spec German engineered vehicles that we own from new, it’s an unattainable utopia. We have to be realistic with our affordability which is why the second-hand vehicle market is an ideal place to find a car that meets your slightly lower expectations and doesn’t require you to break the bank. However, you must recruit the services of a mechanic to conduct a secondhand car inspection to ensure you’re taking care of your investment.

  • Second-Hand cars have been on the road and driven by other people which means it’s normal to find that it requires minor repairs. Usually, the seller shares that information and adjusts the selling price accordingly. However, a professional mechanic inspects the vehicle with the added benefit of possessing an in-depth knowledge of cars and its components. As a result, you receive a complete report on the vehicle. If there are any hidden issues, you can walk away from the deal and save yourself costly repairs.
  • Before you sign on the dotted line and transfer the money to a seller’s account, consider a classic car pre-purchase inspection to help with the negotiation. If the report demonstrates that there are underlying problems that aren’t visible, you can use it as a tool to negotiate a better price. The seller may disagree and refuse to lower their asking price, at which stage you can end the agreement and save yourself from buying a deteriorating vehicle.
  • ​Aside from the mechanical components of a car, a technician relies on their experience and skills that they developed through the years to determine if the vehicle you’re about to purchase has been involved in a prior collision. It’s easy to cover up the fact that the car has accident damage. After your mechanic has inspected the vehicle, you will have the information regarding any touch-up work done regarding the paint of the car.
