I'm assuming you're using your 2D array to model Car objects, so, essentially each row will model a Car, and each column will model the respective Car attributes (although it would be much cleaner, and object-oriented to simply use a single-dimensional List of Car objects, with the attributes encapsulated in the Car object itself). Anyhow, using the 2D technique, you can have something as follows:
Realize, this is an awkward way to define Car objects, so if you need not use a 2D array, don't.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
