An $800 solution for basically any vehicle one is likely to encounter here at DMS:

Reviews seem to be favorable:

Plenty of YouTube demos of the unit to show what it can do.
“Snap on” is nice, but not the solution - and certainly NOT for the DMS.
There are more options with far better coverage and far less money than Snap On could ever deliver.
Getting something like Zach (above) or autoenginuity or similar that will work(really well) with Asian, Euro and the two American manufacturers would be nice!
Questions about them would be:
One time purchase?
Monthly or yearly fees?
Actual support here in North America?
Options - i.e. what does it come with or not come with, cables (esp for non OBDII cars) etc.
It would be nice to have a smoke machine and a 5 gas analyzer…
I see what you did there.
