I would say there is no replacement for a factory scan tool, but unless u specialize in one particular make its prohibitive to buy them... Yeah it does let you do some additional stuff that Genesis didn't, PATS programming for lost keys etc... Which may be a benefit in your business.. did you look at the AE website? it has a pretty good list of what it will do. Occasionally it doesn't always display a value (calculated load) doesn't work on my 7.3 diesels... but you will find quirks like that with all scan tools. no connectivity issues per se... Except yesterday on ym 02 F350 but that is cuz the OBD/cigar lighter fuse was burned out


worked fine after that. did contribution test with it and found the bad injector.... If you are specifically looking at the 7.3's or any other vehicle that Minotaur will access then anything you can't do with the scan tool can be done with custom tuning. (in essence you are going beyond a factory scan tool)
I Haven't done anything with the on board tire pressure monitoring systems so I am not sure AE supports any of those functions or access.
I would love to chat with you more as I am considering getting an auto dealers license here in Colorado... (looking for a new business venture

)
One thing with AE is you are paying for the software only, unlike a scan tool where you also are paying for the hardware to run it. I have AE, Minotaur, Alldata etc. all on my netbook which is real handy
