Hi Ronin6.9, firstly please let me welcome you to TK. It is hoped that you will like the site - at times, we're getting away a little bit from matters pertaining to our 116s and 107s, but the cars are a little thin on the ground, so I try and find other means to make the site more readable and, hopefully, ultimately more interesting.
Regarding your query concerning the genuine lip, and also the AMG reproduction spoilers. The genuine units really have shot up in price over the years, and whilst I have not checked for some time, they may not even be available any longer. I do have a replacement unit in stock - used, and maybe about 65% condition, priced at $180.00, plus postage and packing. They are awkward units to pack and AP will not take them.
The alternative would be to opt for one of the AMG reproduction spoilers - I have one on hand, and the price is still $375.00 unpainted, plus packing and postage. I can get you a price for cartage. The cost of packing: $55.00.
Personally, I much prefer the frontal appearance with the AMG spoiler. I'll see if I can dig up a photo for you. Regards Styria
