Lumma Design bodykit

[Solidgold]

Hi, just got myself a 1.5 yr old E70 3.0si. Been surfing the web for additional add-ons. Seen some very nice Lumma Design body kits. Was wondering any folks out here have it installed on your ride?

How is it? And how much will it cost you to do just body kits (front, side skirts and back bumper). Can you do it without the changing your exhaust since I notice that the valance is cut with a diff specs from mine current exhaust.

Also, been getting very poor petrol consumption. 6.0-6.5km/litre. Is that normal?

Thks for the patience and would welcome any suggestions or help.
