Hi guys, I've not owned an Audi for a while but my father has a 1991 Audi 100 Avant Turbo sitting in his drive that hasn't been used in at least 3 years. He replaced it with a 1995 A6 2.5TD because he wanted something diesel. I'm just wondering if it is worth anything? It has about 120k and was always looked after before it became a garden ornament. It starts and runs but has a petrol leak. The bodywork has very little rust but has green stuff growing on it from sitting so long! We'll get £200 scrap for it locally but since the petrol turbo seemed to be a bit rarer than other models I thought it might be the sort of thing that could be used for parts? Anyone hazard a guess at value?
