I'm thinking of buying a 1997 Maxima with 75K. Is there anything special I should take a close look at before I buy? At the same time I want to sell my 1989 Maxima with 188K.

just take it to a dealship and have them look at it for $95. It is the best thing you can do. i Took mine in, and paid my $95, and the found about $2700 worth of stuff that had to be fixed. i worked it out with the delaship and it saved me over 2 G's doing it.
