I believe this was in an older issue of some audio magazine (the name escapes me at the moment, but I'll find out). It's an E36 M3 and the guy who did the mods did it to show off his companies new line of Alpine products. I believe it took him almost a full year to do all of the modifications (inside and out). It is an amazing car! I believe the only thing stock on the interior is the headliner.
