Best used buy
Audi A3
A3 for broader parts support and a more practical shape; CLA when condition, specification, and gearbox behavior justify the styling premium.
The A3 is usually the rational purchase. A clean CLA can still be appealing, but neither car excuses weak dual-clutch behavior or missing maintenance records.
Key differences
- CLA trades rear visibility and access for coupe-like styling.
- A3 offers stronger hatchback and saloon practicality.
- Both have engine-generation-specific timing and cooling risks.
- S tronic/DSG and 7G-DCT histories need evidence.
Buyer advice
- Drive from cold and test low-speed clutch engagement.
- Check water ingress, infotainment, and warning history.
- Price tires and brakes before choosing high-spec wheels.
Red flags
- Clutch judder
- Coolant residue
- Misfires
- Dead infotainment
- Uneven tire wear
