Our Verdict
Proceed with considerable caution. This
With a car of this vintage, the MOT pass alone tells only part of the story. The advisories from the 2023 test specifically flagged corroded front coil springs and corroded rear suspension components — these are structural items that, if left unchecked, will eventually fail and result in an MOT failure rather than an advisory. By the time of the 2024 and 2026 tests, these items no longer appear, but that does not mean they have been rectified; they may simply have been missed or deprioritised. Ask the seller directly for evidence that the corroded suspension parts were replaced or treated after the 2023 advisories.
Given the engine size of nearly 3.0 litres and the car's age, parts availability can be mixed. Some trim and rubber components may be increasingly hard to source, and specialist labour rates will apply. Negotiate accordingly and budget for likely suspension refurbishment, brake overhaul, and tyre replacement as immediate priorities. A pre-purchase inspection by a marque specialist is essential — budget around £150-£250 for this and treat any seller refusing an independent inspection as a red flag.
Running a 34-year-old 3.0-litre Mercedes-Benz is unlikely to be cheap. Fuel economy on a car of this age and engine size is realistically in the low-to-mid 20s mpg at best, so fuel costs will dominate the budget. Insurance is likely to fall in a moderate group for a classic, but limited-use policies (which suit cars of this age) can keep premiums sensible. Road tax for a pre-2001 vehicle of this engine size will be the standard pre-CO2 based rate.
Maintenance is where the real costs lie. Older Mercedes vehicles of this era benefit from specialist attention, and labour rates at a marque specialist are typically higher than at a general garage. Expect an annual maintenance budget comfortably above that of a modern equivalent, even for routine servicing. Estimated annual running costs are likely in the region of £1,500-£2,000, factoring in fuel, tax, insurance, and a realistic maintenance allowance for an ageing vehicle.
The 2023 MOT recorded corroded front coil springs and various corroded rear suspension components — these should be your top inspection priority. Jack the car up (or have it jacked) and visually inspect the springs for pitting, flaking, and section loss. Tap them with a screwdriver; a healthy spring will ring, a corroded one will produce a dull thud. Pay particular attention to the rear suspension arms, bushes, and subframe mounting points, as corrosion here can become a structural concern on a car of this age.
Beyond the items flagged in the MOT history, inspect the rest of the underside thoroughly for corrosion. Check the sill seams, wheel arches, jacking points, and any boxed sections for bubbling paint or visible rust. Examine all tyres carefully — the MOT history shows multiple tyre wear advisories at the last three tests, which could indicate alignment issues, suspension geometry problems, or simply infrequent rotation. Also check the condition of the brake discs and pads, the exhaust system for leaks and corrosion, and all fluid levels. Finally, verify that the car starts cleanly from cold, as 30-plus-year-old fuel systems can be prone to leaks and vapour lock issues.
This brown Mercedes-Benz 300 was first registered in January 1992 and is powered by a 2,962cc petrol engine. The MOT history shows three recorded tests, all of which passed, but recurring advisories around tyre wear and significant corrosion on front coil springs and rear suspension components point to age-related deterioration. Mileage has risen from 102,448 in May 2023 to 112,738 in March 2026, an increase of roughly 10,290 miles over three years. The combination of advanced age and visible corrosion on critical suspension parts warrants careful scrutiny.
No aggregate MOT data is available for the Mercedes 300, so broader reliability patterns cannot be confirmed from the dataset. The individual record shows age-related corrosion on suspension components, which is consistent with what is typically seen on vehicles of this era regardless of marque.
