The MUCAR CDE900 OBD2 Scanner is a nice step-up from your basic code reader if you’re looking for one with a nice touchscreen and options for analytics. For the $50, it’s a good price for an OBD2 code reader. Personally, I wouldn’t fork out the additional $40 for the extra data you can pull from your vehicle unless you truly needed it. I didn’t find the special functions from the add-on particularly useful, but it’s something you might need if you’re trying to diagnose something wrong on your vehicle.
