What a 2020 A-Class is advertised for

Asking price

$32k to $50k

Odometer

40k to 90k km

Asking prices, not sale prices: the middle 60% of the 335 advertised in the last 12 months, one listing per car.
- Get the rego or VIN From the ad or the seller. Enter it at the top of this page: the make, model and year should match the ad.
- Compare the price With what similar cars are advertised for.
- Ask the seller How long they have owned it, why they are selling, any accidents and any money owing.
- Ask for the service book And for the engine to be cold when you arrive.
- Meet in daylight In dry weather. For a private sale, at the seller's home: the address should match the registration papers.
Inspection

- Panels and paint Uneven gaps, paint that does not quite match and overspray on rubber seals point to accident repairs.
- Rust Under the doors, around the wheel arches and under the boot floor.
- Tyres At least 1.5 mm of tread, even wear across each tyre, and a spare.
- Glass and lights No chips or cracks in the windscreen, and every light works.
- Oil and coolant Check them cold. Milky oil under the filler cap, or oil in the coolant, can mean a head gasket fault.
- Cold start Watch the exhaust and listen for rattles in the first few seconds.
- Wear inside The pedals, steering wheel and driver's seat should fit the odometer reading.
- Warning lights and controls Lights come on with the ignition and go out once the engine runs. Try the air conditioning, windows, locks and screen.
- Flood signs A damp smell, water marks or silt under the carpets.
What to check on a A-Class
- Service history Confirm oil changes at correct intervals with MB-specification oil; absence of history is a red flag on both generations.
- Cold-start rattle (W176) Listen for a metallic rattle in the first few seconds on a cold start; any rattle warrants a timing chain inspection before purchase.
- DCT behaviour (both) Test in slow stop-start traffic when the car is warm. Persistent jerking, slipping, or thumping points to clutch pack or mechatronic issues.
- MBUX and battery (W177) Cycle through all MBUX screens and pair your phone via Bluetooth. Check whether the 12V battery has been replaced recently and why.
- Coolant and thermostat area Look for white residue or staining around the thermostat housing and confirm coolant is clean, not brown or rusty.
- Recall status Check that Takata airbags (W176) and any outstanding W177 recalls have been rectified by a Mercedes-Benz dealer.
The A-Class's known problems, in full
Test drive
0 of 5
- 20 minutes or more On slow streets and at highway speed.
- Steering and brakes It runs straight with your hands light on the wheel, and stops straight without shudder or squeal.
- Gear changes Smooth, with no slipping or flaring revs. In a manual, a clutch that bites near the top of the pedal may be worn.
- Noises Knocks over bumps, and whines or hums that rise with speed.
- Temperature and leaks The gauge settles and stays put. After the drive, look under the car for fresh drips.
Paperwork
0 of 7
- Money owing A car with finance owing on it can be repossessed after you have paid for it. A PPSR check shows it.
- Write-off A statutory write-off can never be registered again, and a repairable write-off needs an inspection first.
- Odometer Compare the reading with earlier records of the car: service book stamps, earlier listings and other records.
- VIN match The VIN on the car matches the registration papers and the PPSR certificate.
- Seller's licence The name and address match the registration papers.
- Safety certificate In Queensland the seller needs a current safety certificate, and in Victoria a roadworthy certificate is needed to transfer the registration.
- Receipt The date, the price, the VIN and rego, and both names and signatures.
Money owing and write-offs on the A-Class

19% had money owing

21% were recorded as written off

Of about 350 used Mercedes-Benz A-Class checked on Carify since November 2023. Every car checked: 9% had money owing and 13% were written off.

These are cars people chose to check before buying, so they are not a share of every A-Class on the road. Money owing is what was registered against the car on the day it was checked.
Where to find the VIN on a Mercedes-Benz

C-Class (W205) · where to find the VIN
1. 1. Door pillar, driver's side. Open the front right-hand door to see the plate.
2. 2. Floor, under a carpet flap. In front of the driver's seat. Slide the seat right back first.
Drawn on one Mercedes-Benz model: others may differ, and the owner's manual lists the places. Reading a Mercedes-Benz VIN

Older cars also carry a compliance plate, usually under the bonnet or on a door pillar. A car supplied new since mid 2021 may have none: it is entered on the Register of Approved Vehicles instead.
