Just got back from Auto Zone and they have way more Metric tools than anyone else locally and at great prices. I found the MB special O2 sensor tool for $8 and few 12mm, 14mm and 17mm hex bit allen sockets all 3 for $7... all with lifetime warranty. Same stuff from a "specialty" european auto parts or web site will cost 5x more... I guess it all depends on how serious about tools you get and how often you need to use it: If i was a pro mechanic, then I'd probably get the more expensive stuff since I know it'll pay off in the long run as people pay big $$ to get their cars fixed and having the proper tools is part of why mechanics charge big $. But for the home DIYer (like me) I'll settle for the "inexpensive" stuff as long as it gets the job done.
