what extra things can i do to extend the life of my 99' gs300? Its an after work and weekend car, dont drive it that much at all but still want to keep it around for awhile so any advice helps...

 

Just keep the routine maintenance up and don't abuse it and it should last for awhile. You'll always have to replace parts at some point and the engine is pretty solid. Even then you can still have something go on you as my last car blew its engine as the variable timing had a stroke and blew my top end.
