About the 2006 FIAT UNCLASSIFIED

The 2006 FIAT UNCLASSIFIED is a large car with a 2300cc diesel engine. 207 of these vehicles were MOT tested in 2026, making it a less common model in the UK market. Among all cars from 2006, the average MOT pass rate is 73%, and this model beats that benchmark.

With an average of 51,872 miles at 20 years old, FIAT UNCLASSIFIED 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.

2006 FIAT UNCLASSIFIED Fuel Costs

The 2300cc diesel engine offers a reasonable balance between performance and economy. Expect around 40 mpg in mixed driving, which works out to roughly £1,245 per year at current diesel prices of 148p per litre (based on 7,400 miles per year). Diesel cars of this age should have their DPF (diesel particulate filter) checked, as replacements can be costly.

What does it cost to own a 2006 FIAT UNCLASSIFIED?

Total estimated annual running cost is £2,195 183/month), broken down as £1245 fuel, £395 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.

FIAT UNCLASSIFIED Reliability Trend

Newer FIAT UNCLASSIFIEDs show better MOT pass rates than older ones, with an average improvement of 15 percentage points.

Buying a Used 2006 FIAT UNCLASSIFIED

At 20 years old, the FIAT UNCLASSIFIED 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 2021 model has the highest pass rate at 97%.

Common Issues to Watch For

Based on the 2006 FIAT UNCLASSIFIED's fuel type, age, and engine size, these are the most likely problem areas to check.

DPF (Diesel Particulate Filter)

Watch out

Short journeys clog the DPF. Replacement costs £1,000-£2,500. Check the DPF warning light and ask about driving patterns.

Turbo Wear

Watch out

Diesel turbos work harder and wear faster. Listen for whining noises and check for oil leaks around the turbo housing.

EGR Valve

Watch out

Exhaust Gas Recirculation valves clog with carbon deposits, causing rough running and poor economy. Cleaning costs £150-£300, replacement £300-£600.

Dual Mass Flywheel

Watch out

Larger diesel engines put extra strain on the dual mass flywheel. Listen for rattling at idle. Replacement with clutch is £800-£1,500.

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.

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.
