About the 1993 Lexus LS400

The 1993 Lexus LS400 is a premium performance car. Our records list a 3969cc petrol engine, though engines vary between versions. 86 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. Among all models from 1993, the average MOT pass rate is 76%, and this model beats that benchmark.

With an average of 106,151 miles recorded at its 2024 MOT tests, Lexus LS400 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.

1993 Lexus LS400 Fuel Costs

The 3969cc 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 £1,958 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year).

What does it cost to own a 1993 Lexus LS400?

Total estimated annual running cost is £2,888 (£241/month), broken down as £1,958 fuel, £375 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 79% pass rate. Keeping on top of servicing will help avoid surprises.

Lexus LS400 Reliability Trend

Older Lexus LS400s tend to have better MOT pass rates than newer ones, with an average decline of 3 percentage points across model years.

Buying a Used 1993 Lexus LS400

At 33 years old, the Lexus LS400 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 1995 model has the highest pass rate at 85%. Note: with only 86 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

Timing Chain / Belt

Watch out

At 33 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 106k 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.
