Hopefully they're Mercedes and not Volkswagens. Volkswagen is at the very bottom of the IQS rankings, only ahead of Land Rover and Mitsubishi.
My father owned a first generation jetta over 12 years. His first german car was bmw 2002 turbo, he kept it from 1973 till 1976. After that he had an Opel Kadett 1.2s from 1976 till 1988. His first American car was a 1966 Chrysler New Yorker. My father owns a polo since 2000 and it is a great car. The only guy in my family who owned mercedes benz cars was the brother of my uncle who lives in lausanne, he owned a w116 s class from 1976 till 1991 and now he still has his beloved w126 s class. My family in the us is mostly owning vintage and modern gm and mopar cars, exception made of one of my cousins who drives a stang mach 1 fastback with a custom made 428 scj engine.
