Pre-Sale check up?

I am looking to sell my 6 year old Honda city. How can I ensure that I get maximum value of the car. I have serviced the car last month and changed small spare parts that needed to be replaced. What else should I check before putting it up for sale? The tyres are not very old, so I am not looking to change them.

I would go through this used car inspection checklist. If your car passes most or all of these items, you would have a better chance at asking for more money for the vehicle.
