I have a 2001 E320 Mercedes Benz that I work on my self. I am looking for a scanner and comparing iCARSOFT and autoenginuity. Which of this two scanner is worth buying and will work on my E320 W210. I need to get this fixed before next year. I get CEL and flashing fuel gauge light. I also get SRS light. So I want to analyze and fix my car. I also have other cars such as Jetta and old 560SEC. The family alos own Masda, Subaro and Honda. Any time there is a problem, my kids call me. My sister have GLE.

So which is a better buy, iCarsoft or Autoenginuity?
