the american graffiti impala and merc

just wondering what ever happened to them
i know the t bird the 32 and 55 are still around
but cant ever find any info on the 1958 impala and the 50 merc

can i read it without the trial membership?. I have enough people bugging me.

I just recently heard that the '58 was still in tact and was, more or less, in the same shape it was in when the movie was filmed. I want to say that I also heard that it resides in Washinton state somewhere.
