2006 BMW 530itx Bagged Wagon on Air Ride VIP Well executed, one off design

Up is my special 2006 BMW 530itx wagon on full Airlift custom designed suspension. This wagon is very unique in that they do not make an "off the shelf" kit to fit the AWD of the BMW wagon. This air suspension was custom build by the prior owner using countless options in order to come up with the current set up, which is very driveable. This car has spend most of its life on the west coast, specifically California and Washington, so it is free of rust and typical corrosion found here in the midwest. Everything works on the car, though due to the replacement of the stock suspension with the air ride, the auto level control is not working and showing up on the error codes.
Details on this car:
Recent Maintenance: Transmission service and full 150k service done less than 1k ago. New Akebono low dust brake pads front and rear. New panoramic sunroof surround. Recent tune up, check, and oil change 500 miles ago. New battery, front control arm bushings replaced and other bushings checked within 500 miles.
Wheels and Tires: New, one off custom Racing Dynamic vintage centers with true three piece barrels to give maximum width for backspacing. Wheels are 19x10, square all around, powercoated, new centers, and new tires. Wheel builder is well known for extremely high quality work (and also the prior owner of this car). Also have 18 x 7 OEM wheels and tires that can be included.
Air Ride Suspension: Full Custom designed air suspension system. Airlift performance series front struts from MK6 VW. Custom lower sleeve and modified top mount. Airhouse IIs in the rear with all custom bracketry. Airlift V2 management with single Viair 380 and 3 gallon Aluminum tank completely hidden so you can use the full room of the wagon. Tucked neatly into the hidden rear tray away from view, though looks completely professional that you will not be embarrassed to show it off. All wiring and hoses hidden and neatly tucked away.
Other Modifications and Features: Full MTech kit (replica front and sides, OEM rear). Projector foglights with full digital Canbus 4300K HIDs. RPI axleback exhaust (wonderful exhaust tone and not at all intrusive). Full shadowline trim (windows and kidneys). Black/carbon emblems all around. OEM adaptive Xenon headlights converted to euro-spec. OEM BMW window tint installed about 20k miles ago at a cost of $850. Interior trim wrapped in 3M brushed steel vinyl. Stock rims as shown are square 18" OEM with tires of less than 2k miles.
This is a very high quality automobile, one that I purchased for my own use (I love wagons). Its been very reliable and always turns heads. Only reason I am selling is to replace it with an e63 wagon that has caught my eye.
