I will probably be making a road trip within the next month or so to look at some of the 2002+ NSX's that are for sale in the NorthEast area and having never owned or driven an exotic, I don't know what the protocol(s) are. For dealers, does the salesperson always ride along or is it okay to test drive with my girlfriend? Do they need to do any sort of background check, deposit, anything of this nature in order to see if I am qualified? Should I call ahead and arrange for a test drive? Anything else I should know to do/not to do? Is there anything different about a private party sale? Thanks in advance for your advice.
