First bike !

I’m about to close on a deal next week to buy my first bike ever I’m 21 and never rode before, I’m about to purchase a 2017 Honda rebel 500 with about 4k miles and no issues as far as I can tell. I’m really just posting to ask and try to justify if it’s truly worth it, for me to get this bike.

I’m 5,8 and I don’t think I’m going to have a problem on the bike and maneuvering but I also don’t want to spend the money on the bike just to not like it long term, so any tips anyone has would be greatly appreciated.
