Since "best" can mean many things, it is good to refer to more objective benchmarks. On possibility are the defect rates of vehicle types in the same age categories. In Germany, cars must undergo regular official inspections. For new cars it is after three years, then every two years. The largest service company that carries out such inspections is TÜV. Their data from July 2022 to June 2023 for the first mandatory inspection after three years shows that Tesla's Model 3 has a defect rate of 14.7%, ranking it last out of 111 models. (The best was VW Golf Sportsvan having a defect rate of 2,0%.)[1]

However, these figures are subject to two caveats:

- TÜV inspections only cover aspects relating to road safety.

- If a vehicle had a defect before the inspection that was discovered and repaired, this would not appear in the figures. Owners of older vehicles in particular often have them checked by a repair shop before the TÜV inspection because they do not want to risk having to repeat the (chargeable) TÜV inspection.
