To sell or not to sell

Put my last coupe on ebay.ie for sale at a i think reasonable 4k euro and have got some offers but not up at that money (just under 3k).I have spent an absolute fortune (over 9k) on this car but must sell due to work.What is a 16vt,same owner 7 years with a host of extras on it worth in the current climate,on a tightrope on whether just to garage her.Youre comments please
