Pricing

With the 2015 models out, what is a reasonable percentage of the MSRP to expect to pay for a new 2014 model? Does area of the country make much of a difference? (We're looking at buying in Illinois/midwest vs. Florida, as we have homes in both places). Does manufacturer make much of a difference? We're primarily looking at Sprinter-based models with 3 or 4 captain's chairs in the front. Also, we're considering newer used models, but the asking prices we've seen are so close to the pricing for new models that it doesn't make a lot of sense - we've seen new 2014 models priced lower than a used 2013 for the same unit (different sellers, of course). Any advice for a prospective B owner would be appreciated.
