thats the way things go here ... what i do ,if someone call and ask about the price first thing,is i would tell them to come and take a look at the car .. and if they still interested we negotiate the price ... so dont worry my friend ;)
and hey btw a lot of people will call you and sometimes take a look at the car and tell you that they are going to think about it and call you back .. dont keep your hopes on these people ;)

good luck
