FIRST GENERATION ACURA LEGEND COUPE
OWNERS MANUAL
Finally! Due to Honda taking too long to do something about the Acura Legend
G1 manual on their website we, th e community, have taken action!
Here, in its complete form, is the 1987 Acura Legend Coupe manual. Please note
there are 1988, 1989 and 1990 supplementals. Th ey are located at the bottom of the
document, in what I hope to be chronological order. Please notify me of any mistakes I
have made in the creation of th is document. If there are mistakes in the original manual I
am willing to add a community supplemental. Thank you, maytagman.
