It might even wash your socks! Seriously, it is way faster than the SSM II but it's a real PITA to deal with. Full day class at SNE also. Luckily I don't have to worry about borrowing it as I work for Subaru. If you need to blast out CELs, any of the cheapies will probably work. I used the SSM III to troubleshoot an 05 Impreza that had a mechanical overrev and tagged an exhaust valve.
