I'm not that tall (5'10"; maybe 5'11" on a good day

) so I can't speak from personal experience. But there's been a lot of discussion of this on the various TSX sites, and the consensus is that the TSX is an
unusually good car for tall people. Especially if we say "for its size," but even if we don't.
Of course, this is very individual, and the only way to know is to take the car for an extended test-drive (or borrow one for a long stretch). But whenever there's been a thread like this, most of the tall people (even up to 6'5") say the car has been great for them. Usually there are also some posts from shorter people who say :donno: "It wasn't very good for me" :donno: but that's besides the point.
