@mattyrallye - all car sales man try to 'size you up' financially prior to going forward... for some it's something as simple and friendly as "so, what do you do for a living?" others are not so innocuous..
they're all the same, if i were selling desirable goods would i want to to waste my time with people i didn't think could afford it? It's just some are a lot more tactful than others!!
it only gets worse the pricier the goods you are looking at imo, comes with the territory
