Thanks for the info folks. I can currently match Broadspeed on just over 8% and due to issues with my last car getting another £1k off so ends up just over 10% but need to push a bit more as finance rate has gone from 3.9% to 4.9%. I had been wrongly told that the 3.9% was being continued.
Problem is that I already paid an extra £1100 for timing to be re-done on my 320d about 6 months out of warranty but it was a known issue. BMW paid for the parts and half the labour but I felt they shoud have paid entirely so basically Im just about getting that back.I'll try moaning a bit more and see what I can do.
I'm annoyed I didn't move before xmas now but current deal is up in April and had thought spec change might have improved more than just DAB that I wouldnt have specced anyway.
