I guess I am just old fashioned, but I am not driving anywhere that I am not familiar with without programming my Garmin GPS with the specific destination address. And I want traffic alerts on the way, in case I need to detour. The destination guy will know my estimated arrival time, based on the Garmin info and any changes in that time, due to weather, traffic or vehicle malfunctions. I recall the commercial where the guy asks "if you printed out directions to get here, you are in the right place". Several years ago, that would have been me. I would also already have looked at the machine to purchase previously, up close, and the price negotiations would be over. I would have the money in a safe place and ready to pay on arrival, upon seeing the machine as I recalled seeing it before and the seller would be aware that that was the case. I would also bring help with me to move said machine, assuming help was not offered at the destination. So, some guy that doesn't answer messages or give an address would not be on my radar for a perspective purchase, unless it is someone that I know pretty well. But that is just me... Perhaps I am old school, but I am too old to drive 4 hours for something that "might" happen.
