How do I know if my car has CAN bus?
How do I know if my car is equipped with CAN Bus? If the vehicle warns you when a bulb is out, it is equipped with CAN Bus. The easiest way is to contact the vehicle’s supplier or dealership.

No it is not worth the cost. If you live in the states almost all major auto parts chains (Advance Auto, Autozone, etc) will do a check or even loan you the tool for free. Unless you’re checking codes daily, it’s just not cost prohibitive. The error codes produced by OBD2 are rather generic.
