Greg,
I came from a US M3. For the first 30k-40k miles, the car just kept getting better- I might have been breaking in also- getting really used to the car, but it seemed that the engine got smoother, the shifter that had a little notchiness became like butter, and the car was like slipping on an old pair of shoes. Did the M3 get faster/stronger- I dont know. With only 1800 miles, I sense a similar thing with the M5. Only time will tell, but it looks to be a lot of fun!
