show) and the rear bumper ceals are cracked bc of
age.. is 10,500 to much to ask? i have over 14,000

Are you having problems selling it? You didn't mention the model year, so hard for us to judge. Remember you never get back the cost of your aftermarket parts when you sell a car. Expect to get a fraction of the cost back, most buyers want OEM parts. With the bumpers cracked, factor that into the price and deduct the price of the fix.
