Hey Tyson -
Your X5 looks great. The mods thus far are looking great.

But done? How can you be done? There's no such thing as being done.
On the radical side, you can always add the 4.8is or Aero kit along with some 20" wheels. How's about a cold air intake or a performance chip? On the minor mod side, there are aluminum pedals, carbon fiber logos, various floor mats, upgraded bulbs (see group buys), etc. etc. etc. etc.
There is no end. Before you know it, you'll be adding some lambo doors.

But great job thus far.
Regards, Mike
