The newer iDrive seems to be becoming an itch that i need to scratch! This is going to involve either a retrofit - apporx price will be £2k or switching to a newer car with it already on!
Hope much did u manage to pick yours up for if you dont mind me asking and where from? Only reason I ask is that there are loads on the AUC website so if i can go to them with a figure of what i can realistically expect to pick one up for they may be will to do a deal. The new model is due immimently so these cars are losing serious money right now and i feel a bargain could be had!
Re mpg i've not had a chance to drive mine much but doing mostly stop start town stuff ive been getting round 32mpg. not bad but not amazing either, although i am looking into a remap.......
