Let me put it this way bro. Getting a BMW is like marriage.
You get the gal you want, to be your wife (this case, its the UDM. gives you lustful pleasure and juggling act to maintain). Then along with it, packaged together is the father-in-law (the cool factor that tops everything else when owning a UDM), the mother-in-law (the heartache when the car breaks down and the constant niggling issues you'd be faced with), the brother-in-law (the company of people that suddenly becomes an expert trying to racun you to mod) and finally the sister-in-law (the thought of damn-i-should-have-opted-for-the-higher-spec kinda regret that would always be there, as you have to admit, you'll never be satisfied with what you have).
Bottom line : enjoy your ride.
