As a general rule, never believe anything you hear from a dealer until you realize that everything they say is meant to separate you from some of your money. Period.
I said as a general rule. There are always exceptions, and when you find them, cherish them.
Here is a fer instance...
When I was looking for my Road Glide, I found two locally. Both the same color, one a 2008, one a 2009. I tested the 2009 to death. The sales guy was very accomodating. The day before I decided to pull the string, I found one hell of a deal on Craigslist. Problem was, it was in Milwaukee and I live outside of St. Louis. I took the Craigslist ad to the dealer, and said that "in all fairness, I have to show you this". It was also a 2009, at $1700 less than their asking price, and included a Tour Pak. Note: I had already bought one bike from this guy, so we knew each other.
Sales guy took the ad back to the closer dude (the one who does all the paperwork). Both came out and said this... "Dude, you gotta go get this, there is no way we can touch this deal, we just have too much
into our bike". They have been my favorite dealership ever since.
OBTW, this is what I ended up with, from Craigslist, 3 years and 60,000 miles ago....
As for the oil, don't sweat it, just make sure you get fresh in before you ride. Depending on the mileage, you might want to consider all three holes (crankcase, primary, transmission).
