It's a major tactic of car salesmen to delay the selling process repeatedly; it physically and mentally wears down the customer and they are more likely to accept aspects of a deal they don't like, to get it over with and completed.
It seems a lot of the process is slowed by "someone has to run to the registry" type stuff which has to be done in a specific order and during "normal" business hours. Typically the sales guy is eager to finish (just wants to sell his next car) but the paperwork is where things get really slow.
The entire time I was thinking how much of a "waste of time" this all was for the sales guy. He really didn't do much after the initial 2 hours of sales time, just "held our hands" while the paperwork was processed.
