About the 2000 MERCEDES 320

The 2000 MERCEDES 320 is a performance with a 3199cc petrol engine. 39 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. Among all cars from 2000, the average MOT pass rate is 73%, and this model beats that benchmark.

With an average of 92,550 miles at 26 years old, MERCEDES 320 owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

2000 MERCEDES 320 Fuel Costs

The 3199cc petrol engine is on the larger side, so fuel won't be this car's strong point. Expect around 30 mpg in mixed driving, which works out to roughly £1,592 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).

What does it cost to own a 2000 MERCEDES 320?

Total estimated annual running cost is £2,907 (£242/month), broken down as £1592 fuel, £760 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 74% pass rate. Keeping on top of servicing will help avoid surprises.

MERCEDES 320 Reliability Trend

Older MERCEDES 320s tend to have better MOT pass rates than newer ones, with an average decline of 5 percentage points across model years.

Buying a Used 2000 MERCEDES 320

At 26 years old, the MERCEDES 320 is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age. If you're flexible on year, the 1994 model has the highest pass rate at 91%. Note: with only 39 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

Based on the 2000 MERCEDES 320's fuel type, age, and engine size, these are the most likely problem areas to check.

Timing Chain / Belt

Watch out

At 26 years old, check whether the timing belt has been replaced (typically due every 5-7 years or 60,000-100,000 miles). A snapped belt can destroy the engine.

Oil Consumption

Medium risk

Larger petrol engines can develop higher oil consumption as they age. Check the oil level and look for blue smoke from the exhaust.

Rust and Corrosion

Watch out

At 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.

Suspension Bushings

Watch out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Clutch Wear

Medium risk

With an average of 93k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.

Brake Discs and Pads

Medium risk

High-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
