Not only that, but can you trust the original factory software? I know
Toyota's recent problem was hardware (I'm pretty sure), but it could
have just as easily been a software issue.

I'm not sure what country's laws you are referencing. Here in the US,
the laws vary from state to state but in general we don't need to
document any modification made to either software or hardware. Cars in
most states do have to pass a yearly safety and emissions test.

 As for "modified for racing," that could be anything really, but
there are plenty of cars that are super quick right off the show room
floor. And they are not super expensive exotics either.
