It's very possible that's the height. I have a friend who has a 1998 Rexall and his ceiling is about that high.
Take a close look at the storage compartment doors. They have wooden framing inside and the wood can rot and things start to fall apart. At least that's how his is made. Fairly big job to replace all that wood.
If it has been stored inside when not in use, it might be OK.
