Sell Audi A4 2010 white 76k mile

I would like to sell my Audi A4 2010. It is 76000 mile. And according to KKB, such car's price is around $11500-12000.
The car has excellent engine and all the other parts are in good condition. I did a thorough service a few months ago, and the engine is sent back to the dealership to clean and recheck. I fixed all the little problems with Audi car, like lighting, like consuming too much engine oils. So it is like brand new in terms of driving
The only issue with the car is that on exterior side, it has a small hit/scars on the right rear. I asked the body shop that it takes around ~$1500 to fix it to brand new. However I don't think for this old car needs a perfect exterior. But I lower the price by $1000 to reflect this small hits.
