LESSONS LEARNED.
This is the distilled wisdom from$40k+worth of mistakes and mechanical triumphs. These are not just tips; they are the scars and condensed wisdom of 15+ projects. Read them carefully, each bullet point could save you from bad buys, parts, and catastrophic failures.
The Total Cost of Curiosity
The Approx. Financial Leak
The Big Number. Every dollar spent on learning that was not recouped upon sale. The sum total of mistakes and parts.
Bad purchases, statutory write-offs bought by mistake, and mechanical oversights. Direct losses from buying the wrong cars.
Fees, storage, delayed paperwork and the absolute cost of theft losses.
Periodic service, usage wear and tear causing parts replacement, rego, insurance,and.
How Curiosity Bled the Bank.
It started during university winter and summer breaks, driven by a total lack of direction. While my peers were on vacation or binging Netflix, I was under the hood. I began with zero knowledge not even knowing what a 10 mm spanner was, let alone the difference between a statutory write-off and a repairable one.
Rookie mistakes piled up because I was too excited. I bought multiple cars at once, thinking I could juggle them; I ended up juggling three to four projects and creating a graveyard of unfinished cars. Things spiralled, mounting fees, storage problems for cars that did not run, and eventually thefts and vandalism because I could not secure them all. I even registered a business name when cars overflowed, but the commitment and expenses that comes with it forced me to stop.
I bought statutory write-offs without fully understanding the risks and purchased European performance cars without checking parts availability or costs. I lost vehicles to theft partly because I did not prioritise security.
One perk of moving out of home was the freedom to explore anything with no strings attached, an opportunity I would not have had if I had gone back home during vacations. Although my spending exceeded expectations, I did not just satisfy my curiosity about cars; I learned transferable skills and practical mechanical knowledge that I now apply to everyday life.
The Core Realisation
Once you strip a car to its bones, you begin to see the structural soul of everything, not just the surface. True knowledge comes from doing and from making mistakes. That engineering curiosity cost me more than $40k and was self-taught through research and conversations with experts.
Out of all the projects cars, stripping a Mitsubishi Mirage down to its bare bones taught me more than car anatomy. I stopped seeing vehicles as objects and started seeing structures and systems. That ability to read a machines structure translates to tech, finance, and other fields.
Maybe it was always about satisfying a built‑in curiosity. I grew up watching my dad run his businesses, and I have always wanted to understand the why and how of everything. My varied leisure interests combining with my studies gave me a unique lens for seeing connections across other domains.
✓Key Takeaways
- ✓One car at a time: Finish and sell a project before starting another to avoid multiplying costs.
- ✓Prefer Japanese for first projects: Toyota/Honda parts are cheaper and faster to source.
- ✓European = expensive: Expect parts to cost 2–3x more than regular Japanese and have long lead times. Avoid for first projects.
- ✓WOVR matters: Check the wovr register before purchase; statutory/total losses are usually parts/scrap only.
- ✓Avoid performance traps: Turbo systems and performance clutches are high‑cost, high‑risk failures. Avoid for beginners.
- ✓Mechanical health first: Engine and transmission condition matter more than cosmetics.
- ✓Electrical = nightmare: Wiring faults are hardest to diagnose; test every electrical component or walk away.
- ✓Inspect thoroughly: A professional mechanical inspection ($150-$200) can reveal hidden issues and save thousands.
- ✓Storage & security: Plan secure storage (garage/alarms/tracking); parking and storage fees add up and theft is a real risk.
- ✓Contingency buffer: Add 30-40% to worst‑case estimates for unexpected repairs and delays.
✓The Green Flags
- One project at a time
Finish and sell before starting another to avoid multiplying costs.
- Get a professional inspection
Spend $150-$200 on a mechanic inspection to reveal hidden issues.
- Prefer common models
Start with Toyota/Honda (Camry/Mirage): parts are cheaper and easier to source.
- Budget a contingency
Add 30-40% to your worst-case estimate for unexpected repairs and delays.
- Run a PPSR/WOVR check
Never exchange cash without a $2 PPSR report. Check for finance and WOVR status.
- Secure storage & security
Have storage, alarms, or tracking arranged before purchase.
- Prioritise mechanical health
Engine/transmission condition matters more than cosmetics.
- Document teardown
Take a lot of photos (50+ before and after steps); and invest in quality tools (socket set) before major work.
✕The Red Flags
- Project hoarding
Avoid juggling 2+ projects as a beginner, it multiplies storage and costs.
- Buying on emotion/rarity
Avoid purchases driven by looks or rarity without verifying parts/support and costs.
- Buying without checks
Do not purchase without PPSR/WOVR and a mechanic inspection.
- Ignoring electrical issues
Cut wiring, loom damage, or vague electrical gremlins are often catastrophic.
- Starting with performance/European cars
European parts and turbo/performance systems are costly and slow to source.
- Underestimating costs
Do not trust easy fix claims, negotiate based on the next 3 required repairs.
- Statutory write-offs
Treat cheap statutory/total losses as learning projects.
- Buying non-runners without transport
Do not buy a car that will not move unless you have a trailer or transport plan.
Would I do it again?
In a heartbeat. Those $40k+ did not just buy cars; they bought a perspective. I no longer see boxes, I see the structures. Do not be afraid to fail, just be afraid of not learning why. The knowledge and problem-solving skills gained from this leisure pursuit is worth more than what I lost.
Knowledge is the only asset that does not depreciate.
