The full-size luxury sedan that made its debut in Canada in 1990 is bowing out after a 36-year run. It will be offered in a single commemorative edition called the LS 500 AWD Heritage Edition, with only five units being produced for all of Canada. These models feature a new "Ninety Noir" paint finish, 20-inch wheels and a Rioja Red interior. Forget the hybrid: only the 416-horsepower V6 remains available.
