Private Seller Used Car Checklist
A comprehensive guide for inspecting a used car from a private seller. Verify documents, mechanical health, and interior condition before you buy.
Overview
Summary and key details for this checklist.
Buying from a private seller offers potential savings but lacks the consumer protections of a dealership. This inspection process typically takes 60 to 90 minutes for a thorough DIY evaluation. If you are not mechanically inclined, we recommend using this list for an initial screening before paying a professional shop for a Pre-Purchase Inspection (PPI).
A successful inspection focuses on three pillars: documentation (is the title clean?), mechanical integrity (is the engine sound?), and cosmetic condition (has it been in a hidden accident?).

Use the table above as your primary guide during the walk-around. Mark each item as you go to ensure nothing is missed during the excitement of the purchase.
If more than three 'Required' items fail, consider the vehicle a high-risk purchase. Use failures in 'Recommended' or 'Optional' categories as leverage for price negotiation.
