Its all relative, for some peps dollars are like pennys...plus the fact is the owner will likely sell it for more than he paid so its an investment in his eyes.
Everything, including an M3, is a waste of money when the use is for driving on the street and not as a career that bring in an income. We cant use 80% of the power and the handling upgrades are meaningless, but they are fun and we accept that there is a cost to that fun. But a waste none the less.
You should see how the rich and shameless waste their money, this aint nuttin!
