A while back i needed some hard to find air/coolant hoses for my 318. No aftermarket place stocked them so i had to deal with the dealerships. I was really apprehensive thinking i would get screwed price-wise or that they wouldn't give a shit about some old E30. I called up maranello, they ordered the parts for me the next day and it was about $40.
Since everyone was sharing i figured i would throw in too. Awesome parts customer service.
