If you want a used MG4 in Australia because it’s the cheapest way into a proper EV, good instinct. The MG4 is one of the few genuinely affordable used electric cars that doesn’t come with an asterisk the size of a decade-old Nissan Leaf’s battery bill. It’s a real hatchback, not another jacked-up crossover pretending to be efficient, it drives the rear wheels, and reviewers rated it well for the money when it was new. That does not make every used one a bargain. Here’s exactly what you get by variant, what to pay, the warranty catch, and the two things that would make me walk.
What you’re actually buying
The MG4 landed here in 2023 as MG’s first proper electric hatch, and the reviews were kinder than the badge suggested. The Driven’s first drive called it the first affordable, sporty EV to hit Australian roads, and the reason is mechanical: it’s rear-wheel drive on a dedicated EV platform, so it steers and handles like something that cost a lot more. You’re getting a five-door hatch roughly the size of a VW Golf, with a liquid-cooled battery and DC (direct-current) fast charging on every version.
That last point is why the MG4 matters to a budget buyer. The cautionary tale in the cheap-EV world is the older Leaf, whose air-cooled pack degrades faster in Australian heat, and the MG4’s liquid-cooled battery doesn’t share that flaw. If you’re cross-shopping the bottom of the market, it’s worth reading our rundown of the best used EVs under $30,000 before you commit to any one badge.
The variants and batteries: get the right one
MG sold the MG4 in four main flavours here, and the differences are not cosmetic. Battery chemistry, range and charging speed all change as you move up the range. Per Gridly’s model breakdown and Zecar’s 2025 price and specs, here’s the line-up:
- Excite 51: a 51kWh (50.8kWh usable) LFP battery, rated at 350km WLTP. WLTP is the standard lab test cycle used for headline range figures, and real-world driving usually undershoots it. LFP (lithium iron phosphate) is the tough chemistry: more charge cycles, happier being charged to 100% every day, less fussy about heat. The catch is it’s the slow charger of the range (about 88kW peak DC) and it uses a resistive cabin heater rather than a heat pump, so winter range takes a bigger hit.
- Excite 64: a 64kWh (61.7kWh usable) NMC (nickel manganese cobalt) battery, 450km WLTP and a much healthier 117kW DC peak. This is the sweet spot. WhichCar’s long-term Excite 64 saw roughly 350km of real-world range at highway speeds, which is enough to make it a genuine all-rounder rather than a city-only tool.
- Essence 64: same 64kWh drivetrain, rated 435km WLTP, with the gear you actually notice day to day: blind-spot monitoring, rear cross-traffic alert, 18-inch wheels and synthetic leather trim.
- Long Range 77: a 77kWh (74.4kWh usable) NMC pack, 530km WLTP and a three-phase AC onboard charger. This is the road-tripper of the range.
There’s also the XPOWER, the dual-motor hot hatch that Chasing Cars clocked at a claimed 3.8 seconds to 100km/h. It’s a hoot and it’s cheap for the performance, but it’s a different purchase: shorter range, thirstier, and it does not carry the same safety rating as the rear-drive cars (more on that below). If you’re here to save money, the Excite 64 is the one to hunt for.
What a used MG4 costs right now
This is where we have to say something the listicles won’t. Used MG4 prices are squeezed because MG kept slashing the new price. The car that launched at $47,990 plus on-roads in 2023 now starts near $10,000 lower as a brand-new car, and the 2025 range opened at $34,888 driveaway for a new Excite 51. When a new one is that cheap, a used one has to be genuinely cheap to make sense.
At the time of writing, used MG4 listings on carsales run from roughly the high $20,000s for a 2023 Excite up into the low-to-mid $30,000s for tidy 2023 to 2024 Excite 64 and Essence cars, with used XPOWERs sitting closer to $49,000. So the rule is simple: price the equivalent new car first, then only buy used if the saving is real (think several thousand dollars, not a few hundred). We track this across models in our used EV prices for 2026 guide.
The warranty catch you have to get right
MG’s warranty is a genuine reason to buy this car used, but only if you separate two things that MG keeps separate: the vehicle warranty and the battery warranty. Confusing the two is the classic MG trap, and it’s the same one that catches ZS EV buyers.
The vehicle warranty is the long one. Standard cover is 7 years, and from 1 August 2024 MG offers up to 10 years or 250,000km. The extra three years are conditional, though: per Zecar’s breakdown of the two-tier structure, only cars retailed after 31 July 2024 are eligible, and the 10 years only holds if every scheduled service is done on time at an MG dealer. Miss a service and it drops back to 7 years. Most used MG4s you’ll find are 2023 cars, so they carry the 7-year vehicle warranty, not the 10.
The battery is the asterisk that matters, and this is the bit people get wrong. The high-voltage battery is not covered by that 10-year headline. MG warrants it separately, and per RACV the MG4’s high-voltage battery is limited to 7 years or 150,000km, whichever comes first, with a claim only if capacity falls below about 70% of its original figure. So on a 2023 MG4 the battery clock started the day it was first registered and runs out at 7 years or 150,000km no matter how long the vehicle warranty runs. On an older, higher-km car that shrinks the cover you’re actually buying, so price it in.
Two more things. The vehicle warranty is tied to the car and carries over to you as the next owner, provided the service history is complete and up to date, so demand the logbook and stamps. And if the car was ever used for rideshare or as a taxi, it reverts to a 7-year/160,000km term. Ask the question and check the history. The same warranty logic applies to its stablemate, which we cover in our used MG ZS EV guide.
Known issues: what to actually check
The good news first: a search of the Federal Government’s official vehicle recall register returns no active recall for the MG4 as of July 2026, and Australian Car Reviews’ recalls and faults record for the 2023-on car says the same. This isn’t a car with a fire scandal or a pack-failure pattern hanging over it. The complaints that do come up are software, not mechanical.
The main one owners report is the infotainment and driver-assist software. As Sydney owner-tester Neerav Bhatt documents in his running log of MG4 software updates, the early cars can’t take major over-the-air updates in Australia, so the big fixes have to be done manually by a dealer and can take a few hours. Owners have also reported an over-eager lane-keep assist that tugs at the wheel, which MG began addressing with an ADAS update from late 2024. None of this is universal, and none of it is a reason to run screaming, but before you buy, ask when the car last had a dealer software update and take it for a proper test drive on a road with faded line markings to see how the lane assist behaves.
Safety and practicality
The rear-drive MG4 carries a five-star ANCAP rating under the tough 2022 protocols, with 83% adult occupant protection and 86% child occupant protection. Two things to note: the rating applies to the 2WD cars sold from August 2023, and it does not extend to the all-wheel-drive XPOWER. If safety paperwork matters to you (it should), stick to a rear-drive Excite or Essence.
On practicality, the boot is 363 litres in the Excite and 350 litres in the Essence, which is competitive for a small hatch but no cavern. Rear seat space is fine for adults on shorter trips and tight for tall passengers behind tall drivers, normal for the class. Charging is the MG4’s quiet strength: DrivingElectric times a 10 to 80% DC fast charge at 39 minutes for the Standard Range and 35 minutes for the Long Range on a 150kW charger, and Sydney owner Neerav Bhatt’s own 150kW charge test of an Essence 64 tracked with those figures. Either way, it’s quick enough that a highway stop is a coffee, not a lunch.
Whatever variant you land on, get an independent battery health check before you hand over money. It’s the single best few hundred dollars you’ll spend on a used EV, and we walk through exactly how in our EV battery health check guide.
What a good MG4 buy looks like
A used MG4 is a genuine bargain when you find a 2023 to 2024 Excite 64 or Essence 64 with a full MG service history, priced a real few thousand under an equivalent new one. That car gives you rear-drive handling, 400km-plus of usable range, quick charging and a vehicle warranty that transfers with the logbook. For a budget buyer who wants a proper driver’s EV rather than a wheezy appliance, nothing else at the money does what it does.
Two things would make me walk. First, any car with a patchy or missing service history, because the warranty is only as good as the stamps and this is a car whose main weakness is software the dealer has to keep current. Second, an XPOWER bought as a value play: it’s a great toy, but it trades away range and the five-star safety rating, so it’s a want, not a smart-money buy. Get the boring Excite 64 with the paperwork, and you’ve bought one of the best-value used EVs in the country.
Frequently asked questions
Is a used MG4 a good buy in Australia?
Yes, with a caveat. A used Excite 64 or Essence 64 with a complete MG service history is one of the cheapest ways into a modern, liquid-cooled EV with fast charging and a strong vehicle warranty. The caveat is that MG cut new prices so hard that a used one only makes sense if it’s several thousand dollars cheaper than the equivalent new car, so always price the new one first.
What’s the difference between the MG4 Excite 51 and Excite 64?
The Excite 51 has a smaller 51kWh LFP battery (350km WLTP), charges slower at about 88kW, and uses a basic resistive heater. The Excite 64 has a 64kWh NMC battery (450km WLTP), charges much faster at 117kW, and is the better all-rounder for anyone who leaves the city. For most buyers the 64 is worth chasing.
How long is the MG4 battery warranty?
Two separate terms, and this is exactly where buyers get caught. The high-voltage battery is covered for 7 years or 150,000km (whichever comes first), with a claim only if capacity falls below about 70% of new. That’s separate from the vehicle warranty, which is 7 years as standard and up to 10 years/250,000km only on post-August-2024 cars serviced on time at an MG dealer. So the 10-year headline is the vehicle, not the battery: the battery is a 7-year item.
Does the used MG4 have known problems?
As of writing, there’s no active recall listed for the MG4 on Australia’s official vehicle recall register. The common owner complaints are software: early cars can’t take major over-the-air updates locally (a dealer has to do them manually), and the lane-keep assist can be over-eager, which MG started fixing with a driver-assist update from late 2024. Check when the car last had a dealer software update and test the lane assist on your drive.
