Gus,
The Data Card came with the original paperwork from the factory. It is about 3" x 8" in size and the originals are made from sturdy card stock paper. The copy that the Classic Center can send you (they will want written proof of ownership) will be a photo copy from their old records kept on micro fisch(?). It is not very high quality, but it has a lot of information.
Do a Search (upper right hand corner of screen) on "Data Card".
Best of luck with your new 250SL!
