Hi All,
I´ve got a very special and rare "BMW individual set", produced by M GmbH.
It´s a kind of luggage rack that substitutes the back seats.
Pictures can be found here.
These parts have been a limited-lot production by BMW Motorsport GmbH (meanwhile: M GmbH).
Here are the official (german) part numbers and measurements:
1. Producer: BMW Motorsport GmbH
2. BMW-M-No. 4 491 374 (back seat luggage rack)
3. Parts (Measurements and Weight)
a) "Seat" with two luggage racks
lxwxh 1300x600x260 mm Weight ca. 11 kg
b) "Back"
lxwxh 1340x430x200 mm Weight ca. 5,5 kg
c) "middle rack"
lxwxh 450x300x150 mm Weight ca. 3,0 kg
The colour is bright grey and the material is leather.
There aren´t any damages.
The list price of this set has been around 3.500,- US-$ in the early 1990´s. I would sell it for 800,- US-$ plus packaging and shipment from germany.
If you need additional information, please do not hesistate to contact me under ralfberninger@web.de.
Cheers and good driving,
Ralf
