Twenty thousand dollars no longer buys a new car with a proper safety rating, as we covered when the $20k new car died in May. It does buy a very good used one. The trick is buying a small car, not a light one, and checking the build date, because some of the best models skipped emergency braking on cheaper trims.
| Car | What $20k buys | Used Car Safety Rating | Watch for |
|---|---|---|---|
| 1. Kia Cerato (BD) | 2020 to 2022, 45,000 to 85,000km | 5 stars, Safer Pick | S and Sport before May 2021: basic AEB |
| 2. Mazda3 (BP) | 2019 to 2020 G20, 50,000 to 135,000km | 5 stars, Safer Pick | Make sure it's the 2019-on BP, not a BN |
| 3. Toyota Corolla (E210) | 2018 to 2019 petrol, 95,000 to 135,000km | 5 stars, Safer Pick | 2018 listings can be the older model |
| 4. Hyundai i30 (PD) | 2021 to 2022 base or Active, 25,000 to 110,000km | 5 stars, Safer Pick | Base cars built before July 2020: no AEB |
| 5. Mazda CX-3 (DK) | 2020 to 2021 Maxx Sport, 50,000 to 125,000km | 5 stars, Safer Pick | Base cars before August 2018: AEB optional |
| 6. MG3 (new) | New Vibe, $19,990 drive-away in October | Not rated yet; ANCAP 4 stars (2025) | Used ones built before 30 April 2025: 3 stars |
Our analysis of carsales listings on 27 October 2026; Used Car Safety Ratings 2025; ANCAP. All six are P-plate legal in their standard form.
Why your $20,000 should buy used
Only one new car fits the budget, and only just. The MG3 Vibe is $19,990 drive-away under an October cashback, then back to $20,990, according to MG’s offers page. The Kia Picanto starts at $23,390 and the Suzuki Swift Hybrid at $24,990. Used, the same money buys a five-star small car with emergency braking and plenty of life left.
Government data backs that up. Of the 72 Safer Pick models in the 2025 Used Car Safety Ratings, all but one sell second-hand for less than $25,000, the Victorian Government said at the November release. The ratings also show the average risk of death or serious injury in a crash with a 2023-built car is 43 per cent lower than with a 2001 car.
Small car, not light car
This is the one rule worth remembering. Light cars like the Swift, Yaris, Mirage and Mazda2 feel like sensible first cars: cheap to buy, cheap to fuel, easy to park. In real crashes, they protect their drivers poorly, and not one earned a Safer Pick. Every car on our shortlist is a small hatch, sedan or SUV instead.
Light cars
Our shortlist
These ratings come from real crashes, not lab tests. Not one light car earned a Safer Pick in the 2025 ratings, and the 2017 to 2023 Swift, a favourite cheap first car, scores one star for protecting its driver. Spend the same money on a small car instead.

A Safer Pick needs five stars overall, five for driver protection and at least four for other road users and crash avoidance. AEB matters even more for new drivers. A Monash University study found AEB was up to 60 per cent more effective in crashes typical of young drivers. That’s why every pick here has it, if you buy the right build.
1. Kia Cerato: the best first car under $20k
The Kia Cerato is the pick because $20,000 buys a newer, lower-kilometre example than any rival. Expect a 2020 to 2022 S or Sport with 45,000 to 85,000km, plus the balance of Kia’s seven-year warranty, which transfers to the next owner. It has a five-star Used Car Safety Rating and is a Safer Pick.
Check two things. First, S and Sport models built from May 2018 to May 2021 had camera-only AEB that doesn’t detect pedestrians or cyclists, earning four ANCAP stars instead of five, unless the optional safety pack was fitted. Second, run the VIN for recall REC-006395, which covers piston rings on 2020 to 2022 2.0-litre cars.
The 2.0-litre petrol engine claims 7.6L/100km and isn’t fast, which is no bad thing for a learner graduating to Ps. It’s the car to buy if you want the best mix of age, kilometres and warranty for the money. It’s not the car for a buyer who wants a premium cabin; the Mazda3 wins there.
2. Mazda3: the safest small car on the list
The 2019-on BP Mazda3 was ANCAP’s top-scoring small car of 2019, and the 2025 Used Car Safety Ratings called it the best-performing small car. Its ANCAP rating includes AEB that detects pedestrians and cyclists on every variant. At $20,000 you’re looking at a 2019 or 2020 G20 with 50,000 to 135,000km.
Make sure it’s the BP model. The previous BM and BN generations offered AEB only as an option at launch, so stick to 2019-on cars. Early BP cars were recalled for an i-stop software problem that could stop the engine restarting, under recall REC-000895; check it’s been done. The G20 claims 6.4L/100km.
Low-kilometre BPs ask $20,900 to $22,400, so stretch the budget a little if you can, or accept a car closer to 100,000km. The Mazda3 is the right choice for a driver who values safety and a quality cabin above all else, and it’s the one we’d stretch for.
3. Toyota Corolla: the safe bet, at a price
The E210 Corolla, sold from August 2018, is a Safer Pick with AEB that detects pedestrians and cyclists as standard on every variant. The catch is the Toyota premium. At $20,000 you’ll get a 2018 or 2019 Ascent Sport petrol with 95,000 to 135,000km, older and further travelled than a Cerato at the same money.
Watch the listings closely. Toyota sold the previous ZRE182 Corolla as an Ascent Sport until mid-2018, and it’s a four-star car without the same safety tech. The E210 petrol carries the MZEA12R code on its compliance details. 2019 cars were included in a brake booster pump recall, REC-001306, so check that too.
Buy the Corolla if resale and a long reliability record matter most; our most reliable car brands guide explains why Toyota rates so well. Skip the hybrid at this budget, because the ones under $20,000 usually have more than 170,000km on them.
4. Hyundai i30: great value, check the build date
The PD i30 is a Safer Pick, but the base model built before July 2020 has no AEB at all, according to ANCAP. Buy a 2021 or 2022 base or Active model and you get it as standard. Those sell for $16,000 to $20,000 with 25,000 to 110,000km, which makes the i30 the cheapest way into a Safer Pick on this list.
Check the VIN against recall REC-006422, which covers a fuel pump fault on 2020 and 2021 cars that can cause a sudden loss of power. The 2.0-litre engine claims 7.3L/100km. Steer clear of the N Line and i30 N, which are different cars with different insurance bills.
5. Mazda CX-3: if they must have an SUV
If your new driver insists on an SUV, make it a CX-3 built from August 2018, when AEB became standard. It’s a Safer Pick, and $20,000 buys a 2020 or 2021 Maxx Sport with 50,000 to 125,000km. It claims 6.6L/100km, and the high seating position makes parking and visibility easy for a nervous driver.
The compromise is space. The back seat and boot are tight, so it suits a single driver better than one ferrying friends. Mazda recalled the CX-3 and older Mazda3 models for a reversing camera wiring fault that can make the image flicker, so check that on the VIN as well.
6. MG3: the only new car under $20,000
The new MG3 Vibe is $19,990 drive-away until 31 October, and it brings zero history and MG’s 10-year, 250,000km warranty. It is a four-star ANCAP car, tested in 2025, in a guide built on five-star used cars. ANCAP’s chief executive called a driver’s seat latch failure in testing cause for caution.
Be careful with cheap used and demo MG3s. Cars built before 30 April 2025 carry the earlier three-star rating, and every MG3 built from March 2024 to July 2025 was recalled for the driver’s seat under REC-006468. Buy the MG3 for the warranty and the new-car smell, not for crash protection.
The trim traps, in one list
The model badge isn’t enough. These are the variants that look like our picks on a listing but miss the safety tech that made them picks. Ask for the build plate date or compliance details before you inspect, and walk away if the seller can’t tell you.
- Kia Cerato S and Sport, May 2018 to May 2021: camera-only AEB, no pedestrian or cyclist detection, unless the safety pack was fitted.
- Hyundai i30 base, built before July 2020: no AEB.
- Mazda CX-3 base, built before August 2018: AEB optional.
- Mazda3 BM and BN (2014 to early 2019): AEB optional at launch; buy the 2019-on BP.
- Toyota Corolla Ascent Sport, built before August 2018: previous generation, four-star used rating, not a Safer Pick.
- MG3 built before 30 April 2025: three-star ANCAP; check the seat recall.
Cars to skip at this price
The Suzuki Swift, including the Swift Sport, is the one we’d steer first-car buyers away from. The 2017 to 2023 car gets three stars overall and one for driver protection in the Used Car Safety Ratings, and the base GL had no AEB, according to ANCAP. It’s fun, frugal and cheap, but it protects its driver poorly.
Skip the Mitsubishi Mirage too: two stars overall and one for driver protection. Its ANCAP rating dates from 2013 tests, which shows why the tested year matters as much as the stars. And at $23,390, the new Kia Picanto is over budget, and its 2017 ANCAP rating lapsed for new cars at the end of 2023.
Insurance, servicing and the extras
Budget for insurance before you buy. Comprehensive cover averages $2,833 a year for female drivers under 25 and $3,158 for males, according to Canstar’s 2026 data. RACQ says a standard sedan with a high safety rating generally results in lower premiums. Our hot hatch insurance guide shows why turbo hatches cost so much more to cover.
Get any used car inspected, and scan it with an OBD2 reader for stored fault codes. All six picks are P-plate legal in standard form; our P-plate legal cars guide explains the rules. Our first car maintenance checklist covers what to check each month, and the under $10,000 guide has cheaper options.
Our pick
Buy a 2020 to 2022 Kia Cerato with the full safety pack or built after May 2021, and the balance of its warranty. Choose the Mazda3 if you want the highest safety rating and can stretch a little, and the i30 if the budget is tight. Whatever you buy, a five-star small car beats a cheap light car every time.
