Choose-O-Matic advice please

Salespeople are told that they should qualify a customer and find out about their vehicle requirements rather than asking about budget.

This seems to make sense. Have any of you gone in to buy a car, or anything else, and been insulted with the budget question before a salesperson has even asked about how you plan to use the product, or what features you might be interested in?

But even if this is the case, would it be fair to say that you have a rough idea of the amount of money you will be spending on a purchase?

What I need to know, for Choose-O-Matic, is whether we should use a price filter to try and point the consumer in the direction of the right range of vehicles for them to consider. Additionally, if we do include it, should it be the first item in the list for consumers to adjust, or the last item?
