What a 2019 SLC-Class is advertised for

Asking price

$30k to $48k

Odometer

55k to 105k km

Asking prices, not sale prices: the middle 60% of the 154 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.

- 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 SLC-Class
- Operate the Vario roof yourself; multiple times. Cycle it fully open and fully closed, watching for hesitation, warning lights, or incomplete movement. A roof that jams or stutters is a negotiating point at minimum; at worst it signals expensive hydraulic or sensor work ahead.
- Check the hydraulic fluid reservoir (located in the boot area). Low or discoloured fluid indicates a leak or that the system has been neglected.
- Inspect the boot floor and roof storage area for moisture after the roof has cycled. Wet trim or a musty smell points to failed seals.
- Ask for a full service history with evidence of oil changes. On the M274, irregular servicing is the primary risk factor for timing chain issues.
- Check auxiliary battery age on a car older than four or five years, factor in a replacement if it has never been done.
- Test all electrical features COMAND/nav, Air Scarf on both sides, DAB radio, and roof-related warning indicators.
- On the SLC 43 AMG, look for receipts covering turbo servicing and check tyre and brake wear for signs of hard driving.
- Confirm outstanding recalls have been actioned using the VIN at a Mercedes-Benz dealer.
- Run a Carify PPSR check to confirm no finance owing, no write-off history, and no stolen-vehicle flags.
The SLC-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.

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.
