Cervelo P5 £5000 worth it?

Hi guys

I’m looking for a TT bike to do multiple triathlons over the next couple years, with the goal of completing a full iron next year or 2027

Is this Cervelo P5 worth the £5000 asking price? My ideal price range is less than £4000 but for the right deal I’m willing to go over that, this seems really good for my needs and is less than a 30 minute drive from me so I can go and inspect it easily if it seems to good to be true. I imagine if it is a good deal then I’d be able to resell it for a good chunk of the price when I’m done with it anyway, but on the flip side I obviously don’t want to be paying over the odds if it’s not actually worth £5k.

Any thoughts and opinions are much appreciated

Thanks
