It’s the age-old debate — stick with your current wheels or start fresh with something newer? Plenty of Aussie drivers find themselves asking, “How often should you get a new car?” Whether it’s because the repairs are stacking up or the tech’s feeling ancient, knowing when to upgrade isn’t always straightforward.
In this guide, we’ll break down the factors that matter: running costs, resale value, safety updates, and when it’s time to move on before your car starts bleeding money.
Sticker Price vs Real Cost
The purchase price is only the start. What really stings over time is the annual ownership cost — think insurance premiums, maintenance costs, fuel, and the cost of repairs when something decides to quit.
We’ve seen folks get lured in by a good deal on a used car, only to spend thousands in the first year because they didn’t factor in routine maintenance, a dodgy brake calliper piston, or a flat battery mid-winter. That “bargain” turned into a money pit.
Here at Old Cars Removed in Melbourne, we’ve towed everything from rusted-out utes with flat tyres to hatchbacks full of cobwebs and mozzie larvae. We’ve seen it all — from folks clinging to their first car for 20 years to others who swap utes like footy teams change coaches.
From a cost perspective, here’s how the real expenses stack up:
| Cost Category | Average Annual Cost (AUD) |
|---|---|
| Regular servicing | $300–$800 |
| Repairs (major + minor) | $500–$2,500+ |
| Insurance premiums | $900–$1,500+ |
| Fuel (based on gas mileage) | $1,200–$2,500+ |
| Rego & Roadside | $800–$1,000 |
Rule of thumb? If your yearly repair cost or cost of ownership jumps past the car’s resale value — or your patience — it’s probably time to move on.
From Service to Repairs
There’s a sweet spot in a car’s life when it’s cost-effective to keep it running — usually from year 2 to year 7. After that, things get dicey.
Here’s what we mean:
- A minor service might just need an oil filter, a top-up of brake fluid, and new spark plugs.
- A major service? That’s where it gets ugly — transmission failure, steering wheel issues, replacement engine, or even needing a professional mechanic just to start it.
One bloke in Coburg had a 2–3 year old vehicle that was a dream… until he ignored his service intervals. Next thing he knew, the battery pack was toast, the brake lights failed, and he ended up with a dead battery on a long camping trip. If you’re facing constant back-and-forth trips to the service centre, it’s not just inconvenient — it’s expensive.
Fix It Again or Finally Move On?
Here’s the plain answer, based on what we see every day:
- Every 5–7 years: Ideal if you want to avoid expensive repairs, keep tech current, and resale value strong.
- Every 8–10 years: If you’re doing regular car servicing, keeping it clean, and watching for safety concerns.
- Every 10+ years: Only if you’re on bad forest service roads, very light driving, or extremely budget-minded.
Of course, budget constraints play a role. If you’re paying cash for cars on loan repayments, still slogging through an auto loan, or need help with your budget, holding onto a car a bit longer can make sense. Just don’t ignore the signs when the car’s cactus.
Signs It’s Time to Let Go
Not every car needs to explode before it’s time to say goodbye. Some die slow, painful deaths — others just become too much of a hassle.
Keep an eye out for:
-
- Flat tyres or bad tyres that wear too quickly due to poor wheel alignment
- Persistent dashboard warning lights
- Sudden drops in battery capacity
- Delayed response from an automatic transmission
- Frequent jumps at start-up — likely a cold engine issue
- Constantly topping up engine oil, brake oil, or battery fluid
- Clunky starts or strange smells from a combustion-powered vehicle
Even a combustible engine has its limits — once it hits that 90,000-mile mark (around 145,000km for us), things tend to wear out faster.
Buying a New One
Buying a car these days? It can feel like a complicated process, especially with all the configuration options, financing options, and endless dealer upsells.
What to Weigh Up First
- Gas mileage — A newer car might halve your fuel costs
- Annual mileage — High km drivers may need more frequent upgrades
- Safety risks — Older cars might not have even basic modern safety tech
- Autonomous vehicle features — Handy if you want more control over long drives
- Sweet spot — That point where the cost savings of an upgrade outweigh the repair cost of keeping the old one
And remember — a car with a lower sticker price may still end up costing more in the long run if it’s riddled with issues.
Why Regular Maintenance Matters
We’ve said it before and we’ll say it again — regular maintenance can keep a good car running far longer than you’d expect.
Changing your engine oil, rotating tyres, checking air filters, replacing spark plugs and keeping your brake pads healthy is more than just ticking boxes. It’s what separates a working car from a paddock ornament. One tradie out in Dandenong hadn’t done a minor servicing in two years. His brakes were so bad that the brake calliper pistons were stuck open. He said, “It still stops fine” — right before the front wheel locked up outside the servo. Don’t wait for disaster. Stick to your service intervals, trust skilled mechanics, and treat those dashboard lights like they mean business.
What to Do With a Dead Car
When your car’s more rust than metal, or when your repair costs outstrip your budget, it’s time for Plan B.
Here’s what most folks in Melbourne do:
- Sell it privately — If it’s still got rego, and you’re patient (and lucky)
- Trade it in — Dealerships offer less, but it’s quicker
- Scrap it — If it’s unregistered, dead, or has major repairs pending, scrapping it is the cleanest, quickest solution
We’ve pulled cars out of paddocks that hadn’t moved since the 10-year mark, with possums in the boot and spiders under the steering wheel. No keys? No plates? No stress. If you’re in Melbourne, Old Cars Removed will tow it — and yep, you get cash for junk cars in Melbourne.
Melbourne Rego and Council Tips
In VIC, if your old car’s still registered, you might get a refund from VicRoads when you cancel the rego. Just hand in the plates, fill out a form, and you’re sorted. We’ll even take the plates off for you.
Leaving a dead or unregistered car on the street? That’s a big no-no in most Melbourne councils. We’ve seen compulsory rules come into effect fast — and you could get fined or towed.
Avoid the fines. Save the hassle. We’ll come get it.
Checklist: Should You Get a New Car?
Ticked a few of these? Time for a change.
- Over 10 years old
- Repair costs over $1,500/year
- Missed more than two services
- Constant issues starting
- Dashboard lights are on more often than off
- Safety features are outdated or missing
- You’ve outgrown the size or type
If you’ve ticked more than three — yep, she’s probably cactus. No shame in it.
FAQ
How often should I service my car to extend its life?
Stick to the service intervals in your logbook. Usually every 6 months or 10,000km for basic service, and every 12 months or 20,000km for major service.
Is it worth replacing a battery or just scrapping the car?
Depends on the vehicle’s age and condition. If it’s just a dead battery, fix it. If you’re also looking at costly repairs or rust? Probably not worth it.
What’s the most cost-effective age to own a car?
Between years 2 and 7 is the sweet spot — low repair cost, good resale value, and fewer maintenance costs.
Do newer cars really save money in the long run?
They can — especially in fuel, insurance premiums, and avoiding expensive repairs. But always weigh up the cost of ownership against your budget.
Can I sell or scrap a car with no rego and no keys?
Absolutely. We do it all the time. As long as you can prove ownership, we’ll tow it — no rego, no keys, no worries.
