2nd newbie of the day ?

[Dram]

Thought I would also say hello , long time lurker first time poster in motors.

Currently own a E46 M3 and have been very happy with it for the last couple of years.

Question I had for you all is that my local dealer keeps on tempting me with offers on E60 M5's and would be interested to know if anyone had made the change (dare i say upgrade ) and if there was a noticable change in running costs.

Thanks
