Congrats on your new M3 - it's really a very beautiful car. You are being one of the very first few M3 owners in HK. I suppose you put your deposit with BMWHK without even knowing the listed price back in summer 07. I haven't even seeing an M3 in person yet in HK.
You are also the first one who started a thread for HK in the sub-forum. Well done.
I do not have an M3 but it is always my dream car and I'm working hard towards it. Do share more about how you feel about it.
Cheers, and have a nice day!
