Best vehicle plus computer/scanner combo?

An aspect of modern cars that isn't talked about enough and should be is having the tools to access all of the vehicle's computer systems. OBD2 is great, but it only accesses the portions of the vehicle related to emissions. It takes more than a typical OBD scanner for all the other dozens of computer systems in the vehicle. For everything from tuning the engine to fixing modern headlights, these things require make/model specific software.

Some vehicles have great software solutions in the market that provide a very high level of access. Some have almost none at all. I'm mostly curious which have the most access available. But I'm also curious which have very little beyond OBD. Which require very expensive systems, which are cheap, etc.
