For $1600:
* if it throws (a) trouble code(s), it should provide the code(s) to the driver immediately upon request,
and include real-time data visualization and recording for diagnostic expediency, without needing a separate device or mechanic
*should provide 'historically inspired' DIC options (GMT400, GMT800, GMT900, GMTK2xx, GMTT1xx) with increased functionality whenever/wherever possible
basically, you ought to be getting a whole lotta info & abilities for $1600
(I'd prefer a Knight Rider-inspired digital display, 'cause I still think that KITT had more practical functionality than many 2026 vehicles.)
