Help me figure out how much to sell my car for pls

[03cobrarocks]

As much as it pains me to do this, my 03 is going up for sale in a few weeks. Since I am the first owner and have had the car since it was bone stock it saddens me to see it go, but it is time to move on and get a house and work on other things in life for a few years.

What should I ask for it? I was thinking 22k or so hopefully...

Color: Torch Red
Mileage: 54xxx
The new built motor has only been in the car 3k miles or so
I would say the outside of the car is a 7.5 or 8 out of 10, mostly due to paint coming off behind the rear tires and driver side skirt not perfectly fitting anymore.
Interior is a 8/10 with rear seats looking brand new.
