Worth $600

Hi all. I'm relatively new to triathlon and I've done a couple of sprints with a Specialized Roubaix. No real upgrades to it.

I'm looking to get a dedicated TRI bike as I'd like to get into longer distances this year. I know this is an older bike, but the guy seems to have upgraded it a bit and was wondering everyone's take on if it's worth the $600 he's asking. Judging by his Facebook profile, he's done a lot of races and knows his stuff. See details below. Advice?

Cannondale MS2000 (2003) Size 58 Shimano 9ap – Ultegra (front Derailleur, cassette) Dura Ace (Shifters, Crankset, rear derailleur) Wheel options (buyer selects one) – Zipp 404 tubular or Reynolds EC70SL clincher. I will include brand new Tufo S33 tubeless tires, if the Zipp wheels are selected. Shimano pedals included.

Bike was recently service and the chain has fresh wax.
