❓ Frequently Asked Questions About Used Car Inspections
What is the difference between a DIY pre-purchase checklist and a professional PPI?
A DIY inspection checklist covers 80% of visible defects, leaks, worn tires, interior electronics, and road test behavior that you can spot in 20 minutes before spending money. A professional PPI (Pre-Purchase Inspection) puts the car on a hydraulic lift, performs an OBD2 live data stream scan, and checks cylinder compression.
How do I use flagged checklist defects to negotiate the asking price?
Every flagged "Attention" item (such as worn brake pads or tires) costs $100-$300 to service, while "Problem" items (like fluid leaks or suspension clunks) cost $500-$1,200+. Print or present your CarsFixer inspection ledger to the seller to justify a specific, professional counter-offer.
What are the #1 dealbreaker defects when inspecting a used vehicle?
Structural unibody rust, milky oil / blown head gasket smoke, severe automatic transmission slipping, flood water damage under carpets, and active check engine lights with catalytic converter codes are top reasons to walk away immediately.
