BMW 635d This 6 series still drives like an absolute dream. For a 3 litre engine it's surprisingly economical and still goes like a rocket with the bulletproof BMW diesel engine. It's mot'd till Nov 26 with the last mot having no advisories. The car has no faults as seen in the pictures. The body work is in really good condition apart from the bonnet which is starting to fade a bit as also shown in the picture.
