'92 Cutlass Supreme 3.1L

I am new to these forums!

I have a 1992 cutlass supreme 3.1L and would like to start improving its resale value.
Replaced/Installed:
Rear struts(monroe)
front/rear brakes(hi-performance)
Fuel pump/filter (new)
front/rear tires

Would like to do some engine enhancements but do not know where to start, i was hoping to get some ideas on where to start. the car runs pretty smooth and reliable for 230,000+KM!!

K&N air filter (model?)
Lowering springs or spindles(mfg? model?)
performance alternator (for car stereo)
"better quality" battery & new battery cables?

Help please! :disappoin
