This is probably in here somewhere but I can't find it. I'm looking for a good scan tool for my wife’s '06 C230 Sport, Sedan. Check engine light came on as I was leaving Advanced Auto after buying oil for my truck. Guy says we do free scanning. But, their scanner wouldn't talk to the Benz. Went to AutoZone, same deal. Went to NAPA guy says "I’m not surprised". "We're the real deal here". "Why we have the High Speed, Low Drag, Super Mac daddy, High performance scanner". "This little beauty right here will read any car made anywhere in the world". "OBDI OBDII, and it can pull any of the factory Secrete Squirrel codes.
NOT!.
Sooooo……….I’m willing to pay up to like $300.00 for one. Just don’t know which one is good or not.

TIA, Dave
