It really baffles me why Mercedes makes buying their parts so difficult. Even the classic center website offers no way to order parts in a user-friendly way, the way any other successful commercial retailer does. It directs you to some 'epc parts catalog' that you have to pay a subscription for, I mean come on. No wonder alternative sellers do relatively well. It's actually not so different for BMW or Volvo here in the US, just a nightmare to try and figure out how you can buy what you need from the dealer, so I end up buying most parts, including original manufacturer's, from retailers like FCP Euro.
