About the 1996 BMW 735

The 1996 BMW 735 is a premium performance with a 3498cc petrol engine. 115 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It sits in the bottom 93% of 1996 cars for MOT pass rates.

With an average of 109,533 miles at 30 years old, BMW 735 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.

1996 BMW 735 Fuel Costs

The 3498cc 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 1996 BMW 735?

Total estimated annual running cost is £3,107 259/month), broken down as £1592 fuel, £760 road tax, £55 MOT, and £700 predicted repairs. The higher repair estimate reflects the 63% MOT pass rate. Cars in this bracket tend to need work on suspension, brakes, and emissions components.

BMW 735 Reliability Trend

The BMW 735 has maintained consistent MOT pass rates across model years, varying by only 2 percentage points.

Buying a Used 1996 BMW 735

At 30 years old, the BMW 735 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.

Common Issues to Watch For

Based on the 1996 BMW 735's fuel type, age, and engine size, these are the most likely problem areas to check.

Timing Chain / Belt

Watch out

At 30 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

Watch out

With an average of 110k 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.

Higher Than Average Failure Rate

Watch out

With a 63% MOT pass rate, this model fails more often than most. Budget for unexpected repairs and get a thorough pre-purchase inspection.

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.
