Hello, my father wants to buy a used mini (Clubman) as a city car in the Hauruck-Ohne Kopf-Eilverfahren without having any ahung. He wants to spend around the 18000. Is there a certain year of construction which should be avoided, respectively when? What are the diesels? Are they reliable? He is not a diesel fan, but here there is a bigger diesel than gasoline offer. Thanks to you for quick hints, otherwise this goes into the pants and in a few weeks the jamming starts.. Ph
