i was a car parts delivery guy about 10 years ago.i had a friend that worked at one of te body shops that owned a 454 chevelle just like that.i saw his car crumpled up behind his place of buisness one monday. the guy drove into the back of a semi truck.sad loss.but i would go with the 60's model corvette stingray convertibles if i had a choice.of muscle cars. their value goes up faster than most others
