Okay, back to business, new content!
Thanks to Phil from Phils Car Blog for submitting this build. The owner takes his unassuming 4 door E46 318i sedan and stuffs it full of angry M3 goodness. Although it might seem at first that bolt-on items such as bumpers, lights, and panels would be subject to a simple swap-over, it turns out to be quite difficult when small physical differences become apparent. Come and see the owner document the OEM quality transformation from the ground, up.
