Originally it was an
Opel Kadett Caravan
Pretty much famous here in Germany in the 1980`s and beginning 1990`s.
But there are not much of them left as the corrosion preparedness (don`t know how to describe it better) was pretty weak.
Opel used very cheap tin for the bodywork, it nearly ruined Opels reputation and they were suffering at least 10 years or longer from that.
Nowadays Opel uses only the best tin for the bodywork, Audi instead is doing the opposite way -> they are now using the cheapest tin. That won`t be a problem if the cars are completely galvanized as they were a long time.
But Audi learned, that it is much cheaper to galvanize only the "critical" parts
let`s see what the Audis will do in about 10 till 15 years...
