Are service loaners always for sale ? -- what happens if they all sell out at a local SC ? do they keep adding them on and selling them regardless of mileage or do they wait until it hits some magic number of miles? They would always need demos, so what if they sell one with a very small showroom adjustment because it only has 300 miles on it- would they put in another one and incent it's sale ? or would they just say they have no demos for sale ? Also when is the best time to buy a Demo / loaner -- at the end, beginning or middle of a quarter ?
