The only thing I would say is Danny you seem like a decent bloke. But the while thing does seem a little daft. Do yourself a favour and read back through this whole post at what everyone who talks any sense has said. You will not find 1 person that would ever sell their machine in your situation. You want a 500k house and a range rover you need to think a little more outside the box mate. If it's a different story and your telling a little white lie to save face fair enough but if not I'd give it a real good think.
