thanks guys for the kind comments! One more impt reason I chose the z4, like what many of you mentioned, a ECU upgrade costing $500 was able to give me a 100hp gain.
Stock comes 306hp and 400nm torque. one chip, with an intake and intercooler is giving me 425hp and 500nm+ torque now.
Besides the power upgrade, I did up the sound system, which was crap to begin with. My one regret though is not getting a car with iDrive, the LCD in car system.
