Why is the Pre-Purchase Inspection (PPI) Important?

The Secret to Successfully Purchasing Pre-Owned Cars

Pre-owned cars offer a fantastic opportunity to really find your dream car at the right price, and no matter what kind of vehicle you are considering purchasing, one of the most important steps in purchasing a pre-owned vehicle is the pre-purchase inspection (otherwise know as a PPI). Unfortunately, it can be too easy for a buyer to miss out on this important step and many consumers may not even realize how inexpensive and easy a pre-purchase inspection can actually be.

Not only is this inspection process simple, but it has several important benefits for people in the market to buy pre-owned vehicles, such as:

• Reveals hidden problems
• Lets the buyer negotiate the best price
• Allows the buyer to purchase with confidence
• Confirms the vehicles alleged good condition

Plus, this inspection process helps buyers weed out unethical sellers – if inaccuracies are discovered during the pre-purchase auto inspection, the buyer can either re-negotiate or walk away from a potentially bad deal. An expert performing a PPI will be able to provide you with invaluable information, such as:

• Verifying the condition level of the car
• Verifying the proper functionality of the car, its equipment, parts, etc.
• Reveal potential engine or other problems
• Reveal frame damage
• Reveal previous repair work (good or bad)
• Reveal evidence of additional damage (such as fire or flood damage)

In addition to offering Pre-Purchase Inspections (PPI) for luxury vehicles, classic cars, muscle cars, and sport cars, Auto Investigation LLC also offers vehicle appraisals, automotive repair, automotive consultation, and automotive expert witness testimony.
