BMW e39 M5 Dinan Delivery Day

Delivery day for my 2003 Dinan S Carbon Black on black M5. Just arrived from Enthusiast Auto Group. Fully loaded with 78k miles. Dinan CAI, MAFs, exhaust, stage 3 software, strut bar, pedals. The loud vacuum-like start up noise is the air pump in the right front corner re-programmed to be on faster and longer with the Dinan stage 3 software. You can here it eventually go to the normal quieter speed.
