About the 2017 MCLAREN UNCLASSIFIED
The 2017 MCLAREN UNCLASSIFIED is a luxury with a 3799cc petrol engine. 120 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It sits in the bottom 88% of 2017 cars for MOT pass rates.
With an average of 16,105 miles at 9 years old, MCLAREN 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.
2017 MCLAREN UNCLASSIFIED Fuel Costs
The 3799cc 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 2017 MCLAREN UNCLASSIFIED?
Total estimated annual running cost is £2,192 (£183/month), broken down as £1592 fuel, £195 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 81% pass rate. Keeping on top of servicing will help avoid surprises.
MCLAREN UNCLASSIFIED Reliability Trend
Older MCLAREN UNCLASSIFIEDs tend to have better MOT pass rates than newer ones, with an average decline of 7 percentage points across model years.
Buying a Used 2017 MCLAREN UNCLASSIFIED
At 9 years old, this is a solid used buy if you find one with good service history. Depreciation has levelled off, so you won't lose much more value. Focus on condition over mileage.
Common Issues to Watch For
Based on the 2017 MCLAREN UNCLASSIFIED's fuel type, age, and engine size, these are the most likely problem areas to check.
Timing Chain / Belt
Watch outAt 9 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 riskLarger petrol engines can develop higher oil consumption as they age. Check the oil level and look for blue smoke from the exhaust.
Suspension Wear
Medium riskShock absorbers, springs, and anti-roll bar links typically need attention around this age. Listen for clunks over bumps and check for uneven tyre wear.
Service History
Low riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
