Interested New purchase E65

Hi, I’m currently looking for a limousine in XL format. Speaks 7s, A8, Phaeton etc…. A Lexus would also have been nice but it doesn’t exist as a diesel. But should be a diesel, with green badge, automatic, Xenon, Navi, like leather. Drive about 25000 km a year. Car should be with a few kilometers. Maybe a pensioner car or something. The year of construction is less important to me. Have looked at some but are usually not so well cared for, something broken or no green plaque. be found in the net a 730d with 53000 km. It is grey, which I don’t like, but the kilometers are great. It stands with 1900€ in it. How is the 7 so in everyday life of the reliability? Is rust a problem? A colleague of mine has an S 320 CDI, which starts all around … 😉 Are there special flaws there? Had looked at me from the outside a few but not yet sat in a 7er and not driven either. Would be grateful about a few tips from insiders. m Thursday watch because I have free there and can see the car in the bright. Thanks LG
