2010 Cervelo S1 or 2010 Felt F3?

Hey thanks for the reply Mr. Pie!
Yea, I think I’m leaning towards the F3; it’s just an incredible bike.

I will be using this bike primarily for training.

How much does this bike go for now a days?
The original owner has babied the bike and it looks flawless.
It’s my understanding that 2010 was a good year for Felt and that there was a lot of demand for this particular bike back in the days.
Is $1700 steep? I honestly am not sure.
