nonov, you are WAY off on your pricing of M5s. Just two examples:

I'm pretty good with electronics considering I was an electrician on $5million+ yachts.
Get 20k for my Z (lots of mods) and throw some of the cash I have sittin around at it and I could walk away with an M5 tomorrow... I just think a nice down payment on a house would be better in the long run.
