Pop up to knights in Newcastle just off the A500, it's worlds apart. You won't believe they are the same company.
On a side note, parts at BMW in stafford are very good and very helpful, so whilst the sales side of things appears to be lacking, please don't be put off if you do need to visit the parts department.
EDIT: Also too young to be able to afford a 5 series? They do realise they're not exactly expensive cars these days..
Mid spec Mondeo: 22,000
Same spec 5 series: 30,500
Combine that with the fact the BMW will return surperior fuel economy (by quite a margin), servicing (believ it or not) is significantly cheaper on the BMW and when it comes to sell the BMW will have depreciated less.
