About the 2006 Lexus GS

The 2006 Lexus GS is a premium performance car. Our records list a 4293cc other fuel engine, though engines vary between versions. 78 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It ranks in the top 19% of all 2006 models for MOT pass rate.

With an average of 119,533 miles recorded at its 2024 MOT tests, Lexus GS owners drive about as much as the UK average.

2006 Lexus GS Fuel Costs

The 4293cc other fuel 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). This is a petrol-price estimate; running on other fuel will change the cost.

What does it cost to own a 2006 Lexus GS?

Total estimated annual running cost is £3,153 (£263/month), broken down as £1,958 fuel, £790 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 83% pass rate. Keeping on top of servicing will help avoid surprises.

Lexus GS Reliability Trend

Newer Lexus GSs pass their MOT more often than older ones, by 7 percentage points on average, which is mostly down to age and wear.

Buying a Used 2006 Lexus GS

At 20 years old, the Lexus GS 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 2017 model has the highest pass rate at 96%. Note: with only 78 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.

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 120k 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.
