I finally gave up, got my deposit back and bought a CT200H.It is smaller, but surprisingly comfortable. Plus, my wife's car is bigger and we usually use that one with the kids or to haul stuff.
The CT's ride is more responsive than either the Prius or Sonata Hybrid, it brakes in a shorter distance and, given the Prius engine, it is a well tested and reliable technology. We like small hatchbacks in Quebec.
I had not considered Lexus, since I figured I couldn't afford it, but when a friend recently bought one and told me he paid roughly what a well equipped Prius would cost, I had to check it out...
Got to say, service at Prestige Lexus in Brossard is first rate. My rep. is named Yann. Recommend highly.
