Lemon Guard

Screen every used car before you buy. 112-point inspection checklist, automatic score, repair cost estimate, and PDF report.

Buying a used car? Don't guess. Inspect it.

LemonGuard gives you a structured 112-point checklist to inspect any used car before you buy — the same things a professional mechanic looks for, in plain language.

Walk around the car, check each item, add photos and notes as you go. LemonGuard scores the car, flags red flags, estimates repair costs, and generates a PDF report you can share with your mechanic.

The first 3 inspections are free. Unlock unlimited inspections for a one-time purchase — no subscription.

WHAT YOU GET • 112-point checklist covering exterior, interior, engine, tires, electrical, and more • Photo and note capture for every concern you find • Automatic score and grade (A–F) based on your findings • Repair cost estimate for flagged items • PDF export for your mechanic or records • Compare multiple cars side by side

WHY LEMONGUARD A professional pre-purchase inspection costs $100–250. LemonGuard helps you screen every car on your shortlist first — so you only pay for a PPI on the one worth it.
