Clearly I have too much time; used boat sales stat

Okay, yes, I geek out on data/numbers. While looking through the WakeWorld for sale section of used boats <5years old, I wondered what the numbers would tell me.

I copied and pasted into Excel all adds (252) and based on the title grouped them by manufacture (245; I could not identify the manufacture of 7 of them by the title). Of the 245 currently listed below is a pivot of numbers by manufacture. What I'd like to lay over this is the new sales data for the same period by manufacture. To me, this would tell me a % of boats that are being resold. I would guess that Master Craft sold the most boats during that period so the higher number of resales does not surprise me so the % of resales verses new sales would be more telling.

Total Boat
55 master craft
48 malibu

21 nautique
11 tige
6 epic

Does anyone know where to find the sales data? I've done a few quick google searches but I could not locate it.
