Tried to see what they give me for the 2018 V90CC loaner with about 7k miles that sits on the dealer’s lot 
If I buy it at 20% off + $6,750 allowance + $1K loyalty it is almost the same as $41,000 that vroom gives me. But if I get 25% off, then I can make $3k. Anyone want’s to flip it? 
I also apprised a 2017 V90CC loaner with ~6k miles on KBB. Mid-range trade-in is about $500 lower than the listed selling price on dealer’s website. The total discount would be 38% with 25% off before allowances.
