what a change the 54 stopped on me the other day and i had to drive my pt cruiser to work for the first time in weeks. radio air auto was quite a pleasure. the only time i get worried in the 54 is when i have to stop suddenly, i have power brakes but the pedal is so different than the newer cars height wise. amen to the comments about cell phone and all the other things people do while driving. i have 2 red cars and you would think they can be seen, nooooooooo, maybe paint them fire engine yellow they say it shows up much better.
