it depends on what you want 24 inch rims could run u about 850 -1000 and a good plain paint job will be about 500-700 of course subs and amps aren't that much so that should be an pretty cheap fix i had a 2001 crown vic for 3 years and all three years i had it i was constantly adding more and more Accessories to it and all that work probably added up to about $10000 and i sold it for $13000
