no it's not...the woman that works for me, her dad has 3 old, chevelles in his garage (along with a couple/few other classic muscle cars) that are worth at least that much each...heck, the 1970 ss 454 ls6 that he has is worth at least $100,000 all by itself.
my little brother has a '69...it had a 6-banger in it when he picked it up...now it has a built and balanced 396 and an SS hood that he bought at manheim and a few other fun things...cool car...fun to drive!
