What you are seeing right now is the most affordable E60 from earlier models line up at its time, a 520i with M54B22 engine and six speed streptonic ZF6 transmission.
Light mods in front bumper (M5 style) with carbon lip spoiler, rear trunk spoiler, hamman rear bumper & diffuser, plus staggered DPE SC7 20” wheels, turn the lines of non traditional E60’s design into more sporty and dynamic look.
Back in early 2000, this 5th generation of 5 series family was designed by Boyke Boyer and developed by Davide Arcangeli under BMW Design Director Chris Bangle.
I used to hate this car for its “weird” design, and thought it would be nice to just jump over directly from E39 to E60. But let me tell u a wisdom, do not hate something to much or it will comes to (ruin) your life.
