About the 2018 NISSAN 370Z
The 2018 NISSAN 370Z is a performance with a 3696cc petrol engine. 51 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 2% of all 2018 cars for reliability.
With an average of 22,607 miles at 8 years old, NISSAN 370Z 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.
2018 NISSAN 370Z Fuel Costs
The 3696cc 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 2018 NISSAN 370Z?
Total estimated annual running cost is £2,042 (£170/month), broken down as £1592 fuel, £195 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 100% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.
NISSAN 370Z Reliability Trend
Older NISSAN 370Zs tend to have better MOT pass rates than newer ones, with an average decline of 8 percentage points across model years.
Buying a Used 2018 NISSAN 370Z
At 8 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. Note: with only 51 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 2018 NISSAN 370Z's fuel type, age, and engine size, these are the most likely problem areas to check.
Timing Chain / Belt
Watch outAt 8 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.
