prep for selling a car

[ebv8]

just seeing what you all do to get a car ready for sale
and is it worth spending money fixing it up or leave it as is

I have a 2008 FG XT E-Gas with 250,000km
full service history inc handwritten history after 200km

anyway it has some issues cosmetically
small ding in front guard, scratches on the bumper corners and 2 rims gutter scratched
i can get a new guard painted for $220, maybe $500 for bumpers and i can fix the rims but i might be up for $1000 to fix all the cosmetic issues and detail it
mechanically its great and if it needed anything it was always done straight away

its got XR6 limited edition leather trim, XR6 suspension, G6E turbo 18in wheels, G6 grille and its silver so it hides alot of scratches and looks good from 3m away

i want between $4500-5500 for it so will spending $1k on it help get $5500-6500 for it?

or do i just detail it myself and flog it
