How to buy a cheap Mercedes-Benz A Class
The cheapest usable A Classes — 2008 cars, typically 90k+ miles — average £2,037; genuinely sound ones go below that, rough ones cheaper still. The smart money buys the 2017 sweet spot at around £10,592 — 16.6% cheaper than a 2018. A drop that size usually marks a generation change, so check which shape the year buys you — the saving is real either way. Figures from 19,854 real UK price observations, not book values.

Why the cheap ones are cheap
- —Vast numbers were sold on PCP finance, so ex-finance and fleet returns flood the used market.
- —Dual-clutch gearbox fear steers buyers away from the plentiful automatics.
- —Mercedes servicing prices on what is mechanically a small hatch (with Renault-derived engines) puts off cost-conscious owners.
Known issues to check
The documented weak points on used Mercedes-Benz A Classes. A cheap car with one of these brewing isn’t cheap.
7G-DCT dual-clutch problems
The W176's 7-speed dual-clutch has documented judder, hesitation and outright failure (repairs £1,500-£3,000), plus a recall for a faulty gearbox weld on cars built October-November 2015 that could cause loss of drive.
Diesel DPF issues on short trips
The Renault-derived 1.5 diesel (A180d) clogs its DPF on stop-start town use; some 2014-built diesels also had an O-ring fault allowing oil leaks.
Corrosion
Some W176 cars show premature corrosion around wheel arches and the bootlid, unusual for the car's age — inspect panel edges carefully.
Suspension knocks
Owners widely report creaks and knocks from suspension components at relatively low mileages, so listen over rough surfaces on the test drive.
Before you hand over money
- ✓Test the automatic at parking speeds for judder or hesitation, and prefer post-2014 builds outside the recall window.
- ✓Inspect wheel arches and the bootlid seams for bubbling corrosion.
- ✓For diesels, ask how the car has been used — town-only cars need proof of DPF health.
- ✓Full MOT history — recurring advisories are tomorrow’s bills. Our readiness check reads a reg’s real MOT record.
- ✓Write-off check — suspiciously cheap often means Cat S/N history. What the categories mean.
