What is he looking to get for it?

for $3000 I just bought the Roubaix SL3 expert (upgraded carbon and full Ultegra) so he better be giving you a big discount.

I believe the 2012 Roubaix elite was selling brand new for about $2200 (some sites will list at $2500 but should be able to get for at least $2200 including pedals)

I would guess that his bike would be worth about $1200-1500 depending on condition. But remember you'll have no life time frame warranty or LBS support with his used one

and yes, I believe you will find that it is a nice upgrade from your current bike. But I would consider getting a 2012 now while the sales are on unless this guy is giving a great deal to you.
