the way i go is a FULL mixture...
but looks arent that important.... if body damage thats different... id fix that first. but not upgrades.. but thats just me.

first ALWAYS
1. tune up
2. ALARM system!!!!!!!!!
3.speakers if they are blown.. if not bass
4. minor cosmetics
5. performance.


i always do a mixture of all the goodies... performance (which can also be looks under the hood) CAI and header... audio (my name says it all) then some looks and so on what i think is needed or wanted...

i typicaly go by my $$ flow.LOL sometimes good high $$ and sometimes cheap mods.... the cheap ones do add up and make a difference
just think about what ya want to do and be sure ya like it and just DO IT......
just look at the BIG PICTURE.....

but definatly go with what HAS to be repaired or replaced first for reliability! then a alarm system to protect your investment and your future goodies safe... well not always safe but prevents ALOT of thefts!
