Haasman- performance Products, but they have NO selection-just one listing (standard) for my 190D.
The rear shocks (bilsteins) cost me $75 a piece, I think from the benzbin (performance prods had them for $99) plus $10 shipping.
it took me 1 hour to replace the first one, 1/2 for the second one (two screws each, but then you have to compress the old ones to take them out and the new ones to put them in - a pain in da...).
The fact that the mechanic had a problem with the supplier should not affect your price. It's his problem.
