At the time I was only looking for a 3.0is and I ended up with this one as the spec was right and the PX deal for mine was the best I could find.
As for, if the £5000 deal had be on the table at this time I still think I would not have gone for it as I was at the max with money at that time, but who knows! The deal was not there so I was not looking for it.
BTW my BMW 535D is still up for sale at less then the PX
