I don't know if there are still crazy cheap deals on 11sp 105 (<$350 for the entire groupset from the UK sites.) My SL4 frame was a warranty replacement had 10sp 105 on it. I installed 11sp 105 on it myself and sold the old stuff for $250 on Craiglist so it ended up being a pretty cheap upgrade.
Thank you for the detailed response. If that is the case, it's a lot more than what I am prepared to do. I was thinking that $2500 CAD is a good price for this bike seeing that the original price was around $3700 CAD back in 2013. Not sure if he is prepared to sell for less considering its a 2013 model with 10 speed versus the latest 11 speed. I'm positive that the 10 speed is a more than worthy group set.
