2008 Ford Focus 2.5L Petrol · DG58 MWM

The 2.5-litre petrol engine delivers around 30 mpg in mixed driving and drops to low-20s mpg under spirited use, considerably thirstier than smaller Focus variants. Insurance for the ST sits in group 34 to 36 depending on trim, so premiums will be notably higher than a 1.6-litre equivalent — budget £700 to £900 annually for a typical driver. Road tax for a petrol vehicle emitting around 215 g/km will fall in the higher VED bands, and as a pre-2001 vehicle this example is exempt from the standard £165 annual rate, though this should be confirmed at point of purchase.

Routine maintenance costs for the Focus ST are moderate, with front brake pads around £120 fitted and rear discs and pads closer to £250 given the recent advisory. Annual servicing typically costs £200 to £300 at an independent garage. Allowing for fuel, tax, insurance, and routine maintenance, expect total annual running costs of £1,400 to £1,700.

Inspect the rear sub-frame thoroughly for corrosion, both visually and by feel — the March 2026 advisory notes it as corroded but not yet significantly compromising rigidity, which means it should be closely monitored and possibly treated to prevent progression. Check the rear brake discs for lipping, scoring, and pitting, as the failure noted both rear discs worn, pitted or scored, but not seriously weakened. Examine the front suspension components, particularly the anti-roll bar linkage ball joints and track rod end dust covers, which were flagged at the most recent failure. Lift the vehicle and inspect for oil leaks from the engine and gearbox, given recurring oil leak advisories at both 2025 and 2026 tests.

Beyond the MOT findings, check the condition of the timing chain by listening for any rattle on cold start, and inspect the clutch for slipping or juddering, which is common on higher-mileage ST models driven hard. Examine the bodywork for the corrosion that the MOT data suggests is beginning to affect the undercarriage, paying particular attention to wheel arches, sills, and the boot floor. Verify all tyres have adequate tread including the inner edge of the offside front, which was flagged as worn close to the legal limit in March 2026.
