Tvr Sagaris MOT Reliability Overview
The Tvr Sagaris is a niche vehicle in the UK, with 2,112 MOT test results recorded in our database spanning 3 manufacture years. It has an overall MOT pass rate of 87.1% and a failure rate of 12.9%, which is well above the UK average of approximately 37%.
Based on this data, the Tvr Sagaris earns a "Excellent" reliability rating. The average Tvr Sagaris presents for MOT with approximately 27,305 miles on the clock. Manufacture year matters: 2007 models achieve the highest pass rate at 95.7%, while 2006 models have the lowest at 86.6%. This 9.1 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Tvr Sagaris is Lamps, Reflectors and Electrical Equipment, affecting 7.1% of all tests. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. The second most common issue is Exhaust, Fuel and Emissions at 5.5%. Noise, emissions and leaks rounds out the top three at 3.0%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

💡 What does the warranty cliff mean?
The Tvr Sagaris shows a relatively stable failure rate after warranty — the change of 0% is negligible. Peak failure occurs at age 6 (20.2% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Tvr Sagaris MOT Data
The Tvr Sagaris is a niche vehicle in the UK, with 2,112 MOT test results recorded in our database spanning 3 manufacture years. It has an overall MOT pass rate of 87.1% and a failure rate of 12.9%, which is well above the UK average of approximately 37%.
For Tvr Sagaris owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on lamps, reflectors and electrical equipment and exhaust, fuel and emissions for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Sagaris is likely to perform.
Lamps, Reflectors and Electrical Equipment — 7.1% of failures
Lamps, Reflectors and Electrical Equipment issues account for 7.1% of MOT failures on the Tvr Sagaris. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Exhaust, Fuel and Emissions — 5.5% of failures
Exhaust, Fuel and Emissions issues account for 5.5% of MOT failures on the Tvr Sagaris. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
Noise, emissions and leaks — 3.0% of failures
Noise, emissions and leaks issues account for 3.0% of MOT failures on the Tvr Sagaris. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle.
