What about the Green Buick?

I always had the feeling that it had once been a favorite of Dad's, though I have no proof.  This -approximately 1956- vehicle sat in the driveway for years.  It had the "bird's nests" in the fenders (is that what they called them?) and a humpy hood, (maybe it was a 54...).  All I remember is how the roof and hood and trunk would "dent in and out" when we'd land on them with our butts.  They were like spring boards,..  such abuse.  I remember Dad yelling at us for jumping on the cars (there were two, the other was.... uh...) but he got pretty half-hearted about it.  Was it two tone green?  Ka-thoooonk, Ka thoonk, Ka thooonk.
