These cars never had sports car handling, but new shocks can help. For a firmer ride install a set of heavy duty bilsteins

even with only 66k on it, if the timing chain guides have never been done they are due...purely from age.

beautiful looking car! I like that color combination, I just picked up a mint 420 myself a month ago!
