Hmmm...
Looking up Trek Emonda SLR, SL6, or SL8 on E-Bay, and they don't come cheap!!!
Of course the asking prices and selling prices may not always be the same, and on E-Bay, several were sold for "offer".
I very much doubt you'll get the bike for less than $2500, or even $3000, and if you offer $1800, you may get yourself blocked.
