my dad gave me his 92LS400 for graduation and now i'm looking make it my own. The lex. has good speed/acc. for a 170,000 car getting up to 120 was no problem but what can I do to get a lil more out of her. since she's older what should I do as a general tune-up and/or replace for newer parts under the hood?? thanks for your help
