Ends 1/13. Newegg with SpeedShop has the Autel MaxiScan MS300 OBD-II Code Reader for $17 with free shipping. Compatible with 1996 and later OBD II-compliant vehicles, reads and displays Diagnostic Trouble Codes (DTCs). Now you'll know whether you need a new engine or you're just low on wiper fluid.
Good reviews, Good price. Amazon has it for $20 w/FSSS. In for one.
I have one and it's certainly adequate.
