It may be ugly, but it works.

How would you would you specify it to Asymptote? You can't.

You would probably use:

                string[][] cars={{"Mazda","MX-5","1.5"}};

And that's exactly my point: engine displacement may be a number, but
you would have to enter it as a string.

Though, you insist on being able to enter it as a number anyway, hoping
ob-asymptote will do the magic behind. How could it, since the language
can't itself?

Perhaps there should be a way in Babel (not specifically in Asymptote)
to output a table with raw strings. Because want you really want to use
is:

|"1"|"x"|"5"|
|"3"|"y"|"4"|
