Is Bentley's the only option for parts breakdown diagrams? I'm trying to get a good handle on the mechanism in the trunk of my Cabriolet that has to flipped up and down if the top is to be opened. Down for the top to open/up to gain scads of trunkspace. I had posted a question about the mechanism a while back, but there were no responses, just views. I'm trying to avoid the hassle of a return trip to the dealer if possible.
