New year, dream bike

Hi all, I've recently met an old man (ex cyclist, now he can't do it anymore) which Is also a collector, that is selling some stuff.

Bike was in the garage, for the last 10 years at least, he told me that he acquired back in something like the mid 90's from a semi pro Italian cyclist.

As far I can find anywhere online, looks like a vintage Bianchi Reparto Corse El tsx ( It looks like that somebody had fun with a permanent blue marker and some of stickers are missing)

Bike it's mounting a Shimano 600 complete sethubs derailleur, cassette etc. (there's a British guy that owns one and posted a video on YT, apparently this setup was used specifically for the Gatorade team back in 1993)

Chroming in the back side looks a bit fading (I'm pretty sure there's a way to restore it), colour looks 98% in good condition, he told me that last time he use it, his bike mechanic applied some clear coating to preserve the pearliscent Celeste.

He does need a deep cleaning, regreasing etc. Thoughts? For me it's a bargain of a price 300€ and it's my dream bike
