CAN-BUS and Graphic Screens

I was wondering if it is possible if I could use the Arduino Uno to read in from the OBDII port in a car and be able to display onto some kind of color graphic screen such as a TFT or LED screen. I am very capable in terms of software but I have no idea how to deal with any hardware. I was wondering if someone could point me into the right direction where to start with the hardware and the interfaces. Thank you in advance.

I looked in to this just a tad and it seems you can't do it without spending at least $15 on an OBD to serial converter. There are chips but they are more expensive and hard to get. You're better off grabbing one on ebay. Search for "ELM327".

does anyone know if a USB out ELM327 could simply be spliced into an arduino? Or is it more complicated?
