A lot of people who work in the car sales business are scared of the informed buyer
. In my experience this is someone who has wanted to buy my car and knows a good deal about what they want. It is also someone who not only knows this but has some idea of the car they are looking detail such as why the year the model is was a particularly good model or specifics about the car itself. You dont have to be afraid of these buyers if you also know your stuff in regards to the car. I actually feel more confident if someone wants to buy my car and they know a great deal about it, it gives us a point to bond on which then leads to becoming likable to the buyer.
If someone wants to buy my car because they are aware of what a great car that specific model is then it just shows they have good taste. Remember you bought the car at some point likely for a lot of the same reasons. Use the specific advantages of the car as a talking point. Let them know how you have cherished the car and taken care of it because of what a special car it is. Draw backs may still arise. One such draw back could be that the car is not the colour they are looking for, but all is not lost especially in the used car industry as it may be harder to find the model with the specific colour they want at a price they are comfortable paying. Make sure you remind them of this. It is not the colour that makes the car; the car itself as a package is what makes it.
If they dont buy my car for one reason or another and they are an informed buyer it doesnt actually bother me. If it has managed to generate the interest of one person who has a fondness for that particular vehicle then there will be others. Even if you dont find another informed buyer there will be uninformed buyers who you can convert into informed buyers. Once they become informed buyers you have probably converted them into a fan of that particular model for life. Chin up!
