Objective
Build Australia’s largest used-car buyer email database by offering free PPSR before competitors touch the user.
Free PPSR report · ecosystem growth
Own pre-purchase intent with a free PPSR workflow
This workflow was more than a lookup tool. It was designed as a near-zero CAC acquisition engine: offer PPSR free, capture buyer email and phone, verify access, and create the top-of-funnel data layer for downstream Cars24 trust products.
Market demand
600K/mo
Motor PPSR events per month in the reference business case.
Capture potential
15K–22K
Email IDs per month at conservative to upside capture.
Acquisition cost
~$1.50
Cost per email ID captured using the PPSR bulk-rate assumption.
Launch speed
1 sprint
Business case positioned this as near-ready rather than a long build.
Why it matters
Two in three used-car buyers run no check before purchase. Free PPSR becomes the wedge into trust, retargeting, and deeper report upsells.
What it feeds
Service-history upsell, Cars24 retail retargeting, internal data systems, and a reusable buyer-intent database.
Workflow architecture
01
Capture and verify the user
Collect email and phone, verify via OTP, and enforce controlled access so the free report also becomes a structured user-intent record.
02
Check the existing database first
Reuse stored PPSR results before hitting the external API again. This keeps the system cheaper and faster over time.
03
Call PPSR only when needed
If the VIN has no usable cached result, request a fresh check from the government-backed PPSR flow.
04
Store, rate-limit, and grow the database
Save the report, enforce daily limits, and keep building a compounding buyer-intent and vehicle-check dataset.

Business-case snapshot
| Metric | Value | Note |
|---|---|---|
| Total PPSR events / month | 600,000 | Large category demand already exists. |
| Addressable premium pool | 400,000 / mo | Pre-purchase, dealer, and finance use cases. |
| Cars24 capture @ 10% | 15,000 / mo | Conservative email capture case. |
| Upside @ 15% | 22,500 / mo | Higher capture scenario from the brief. |
| PPSR hard cost | ~$22.5K / mo | Main variable cost in the model. |
Conviction: this was framed as a very-high-conviction launch because the product was almost ready, category demand was already visible, and the CAC to capture used-car buyers looked unusually attractive.
Why this page exists in the trust stack
- Free PPSR is the acquisition layer.
- Service history becomes the premium or follow-on trust layer.
- Retail retargeting, seller flows, and B2B products all benefit from the same captured buyer intent.
- The workflow turns a commodity check into a reusable ecosystem asset.
