I am considering snagging up a 850 turbo snow check that a dealer had the buyer back out on. I only have 1 fear.....resale. Will it be worth nothing after a 1 or 2 seasons like the sleds with aftermarket turbos? If I spend 4k more for the turbo'ed 850, will I get half that back out of it after 2 years, or will it be worth the same as an equivalent non-turbo 850 summit?
