I'm going to keep it relatively simple on this one. I've modded pretty much all my cars to a degree in the past. from wheels and coils all the way to spending a small fortune on tracking out the VX220. keeping the Z4 OEM looking but just making some better changes like suspension, possibly brakes and some nice interior touches...... Thats said I've always had that intention then go silly.
I'm wanting a ZMC in about 18-24 months so would be silly to spend too much on this one.
