Water gets into my 2002 WV polo tail light assembly, corrodes connectors, short circuit one of the lamp.
Car still work perfectly fine, changing the corroded circuit with a wire and replacing the light myself cost less than 5€, making new joint in the assembly to avoid more water another 5€.
Fuck new cars, my city is now forbiding my car to go downtown and plan to extend the exclusion zone in the next year. It's only based on the age and type of motor, not on the real consumption/emission ... I will probably have to buy new car soon with all this crap.
