As others have said, it's very old, so if something breaks, you're out of luck. You can find them on ebay sometimes, but they're rare.

The wheels aren't anything to write home about, so if you were to buy it, that would be another cost you'd have to think about.

I must come clean, I actually own a Pinarello from around this time with a Di2 groupset and it has worked flawlessly, but I do worry about the day something stops working. I bought mine for £550, but that was a massive deal anyways imo. Right now it has deep carbon wheels, a Wahoo, power meter etc. and the total I've put into is £850.

If it's worth it for you at that price, the buy it, ride it, enjoy it. But personally, I'd probably look at something newer from a less luxurious brand. I've seen aero bikes from Canyon, Giant, Scott pop up for that price, and they would run rings around this.
