About the 1990 BMW 518

The 1990 BMW 518 is a premium with a 1796cc petrol engine. 38 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It sits in the bottom 86% of 1990 cars for MOT pass rates.

With an average of 88,970 miles at 36 years old, BMW 518 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.

1990 BMW 518 Fuel Costs

The 1796cc petrol engine offers a reasonable balance between performance and economy. Expect around 36 mpg in mixed driving, which works out to roughly £1,327 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).

What does it cost to own a 1990 BMW 518?

Total estimated annual running cost is £2,197 (£183/month), broken down as £1327 fuel, £315 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 71% pass rate. Keeping on top of servicing will help avoid surprises.

Buying a Used 1990 BMW 518

At 36 years old, the BMW 518 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 2015 model has the highest pass rate at 90%. Note: with only 38 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

Based on the 1990 BMW 518's fuel type, age, and engine size, these are the most likely problem areas to check.

Timing Chain / Belt

Watch out

At 36 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.

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 89k 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.
