Girls is the first impression Crucial?

Say you're in college and you get to know a dude who's below ur standards like socially awkward no grooming bad grades average body and lools like he doesn't have 5$ to treat you for a coffe.
Throughout the years he gets slightly better and better till he's the opposite of everything I just said by the last semster his grades are better he looks better can hold an interesting convo gets shredded rolls in a nice car has a nice place and already working a well paid part time that will hire him full time when he graduates

And he makes his move would u like him or will the first impression eww no be the answer?

Also if u think taht if his current version is what matters what would be more attractive if u see him gradually become a better person or if he Disappeared for a while and surprised u with His new self?
