There’s simply no average driver on the road.

Everyone is an individual. Therefore, individually collected impressions are relevant. A car or its components are evaluated individually by drivers and mechanics. Everything that evoked a positive or negative remark will be recorded.

Do the brakes squeak? Do the doors open easily? Does water come into the car? Is there any leakage? Are there unexpected trips to the mechanic? Relevant topics are judged by normal drivers and experts. Comments start with: “beyond my expectations—I’m really happy” and end with: “security risk—I’m considering legal action against the manufacturer”. All this is recorded in a 10-point outline (Subjective Evaluation Index – SEI).
